Someone says that the blockchain in the phone is marketing. This is possible for most applications, but not for Tkeycoin. Today we will talk about how the blockchain works in the TkeySpace app.
Who else is not in the topic, TkeySpace is a financial application for decentralized and efficient management of various cryptocurrencies, based on a distributed architecture without using a client-server.
In simple words, it is a blockchain in the user’s mobile device that excludes hacking and hacker attacks, and all data is encrypted using modern cryptographic methods.
https://preview.redd.it/8uku6thlrtx41.png?width=1280&format=png&auto=webp&s=e1a610244da53100a5bc6b821ee5c799c6493ac4

Blockchain

Let’s start with the most important thing — the blockchain works on the principles of P2P networks, when there is no central server and each device is both a server and a client, such an organization allows you to maintain the network performance with any number and any combination of available nodes.
For example, there are 12 machines in the network, and anyone can contact anyone. As a client (resource consumer), each of these machines can send requests for the provision of some resources to other machines within this network and receive them. As a server, each machine must process requests from other machines in the network, send what was requested, and perform some auxiliary and administrative functions.
With traditional client-server systems, we can get a completely disabled social network, messenger, or another service, given that we rely on a centralized infrastructure — we have a very specific number of points of failure. If the main data center is damaged due to an earthquake or any other event, access to information will be slowed down or completely disabled.
With a P2P solution, the failure of one network member does not affect the network operation in any way. P2P networks can easily switch to offline mode when the channel is broken — in which it will exist completely independently and without any interaction.
Instead of storing information in a single central point, as traditional recording methods do, multiple copies of the same data are stored in different locations and on different devices on the network, such as computers or mobile devices.

https://i.redd.it/2c4sv7rnrtx41.gif
This means that even if one storage point is damaged or lost, multiple copies remain secure in other locations. Similarly, if one part of the information is changed without the consent of the rightful owners, there are many other copies where the information is correct, which makes the false record invalid.
The information recorded in the blockchain can take any form, whether it is a transfer of money, ownership, transaction, someone’s identity, an agreement between two parties, or even how much electricity a light bulb used.
However, this requires confirmation from multiple devices, such as nodes in the network. Once an agreement, otherwise known as consensus, is reached between these devices to store something on the blockchain — it can’t be challenged, deleted, or changed.
The technology also allows you to perform a truly huge amount of computing in a relatively short time, which even on supercomputers would require, depending on the complexity of the task, many years or even centuries of work. This performance is achieved because a certain global task is divided into a large number of blocks, which are simultaneously performed by hundreds of thousands of devices participating in the project.

P2P messaging and syncing in TkeySpace

TkeySpace is a node of the TKEY network and other supported networks. when you launch the app, your mobile node connects to an extensive network of supported blockchains, syncs with full nodes to validate transactions and incoming information between nodes, so the nodes organize a graph of connections between them.
You can always check the node information in the TkeySpace app in the ⚙ Settings Contact and peer info App Status;

https://preview.redd.it/co1k25kqrtx41.png?width=619&format=png&auto=webp&s=e443a436b11d797b475b00a467cd9609cac66b83
TkeySpace creates initiating connections to servers registered in the blockchain Protocol as the main ones, from these servers it gets the addresses of nodes to which it can join, in turn, the nodes to which the connection occurred share information about other nodes.

https://i.redd.it/m21pw88srtx41.gif
TkeySpace sends network messages to nodes from supported blockchains in the app to get up-to-date data from the network.
The Protocol uses data structures for communication between nodes, such as block propagation over the network, so before network messages are read, nodes check the “magic number”, check the first bytes, and determine the type of data structure. In the blockchain, the “magic number” is the network ID used to filter messages and block traffic from other p2p networks.
Magic numbers are used in computer science, both for files and protocols. They identify the type of file/data structure. A program that receives such a file/data structure can check the magic number and immediately find out the intended type of this file/data structure.
The first message that your node sends is called a Version Message. In response, the node waits for a Verack message to establish a connection between other peers. The exchange of such messages is called a “handshake”.

https://preview.redd.it/b6gh0hitrtx41.png?width=785&format=png&auto=webp&s=0101eaec6469fb53818486fa13da110f6a4a851d
After the “handshake” is set, TkeySpace will start connecting to other nodes in the network to determine the last block at the end of the required blockchain. At this point — nodes request information about blocks they know using GetBlock messages — in response, your node receives an inv (Inventory Message) from another node with the information that it has the information that was requested by the TkeySpace node.
In response to the received message, inv — TkeySpace sends a GetData message containing a list of blocks starting immediately after the last known hash.

https://preview.redd.it/lare5lsurtx41.png?width=768&format=png&auto=webp&s=da8d27110f406f715292b439051ca221fab47f77

Loading and storing blocks

After exchanging messages, the block information is loaded and transactions are uploaded to your node. To avoid storing tons of information and optimize hard disk space and data processing speed, we use RDBMS — PostgreSQL in full nodes (local computer wallet).
In the TkeySpace mobile app, we use SQLite, and validation takes place by uploading block headers through the Merkle Tree, using the bloom filter — this allows you to optimize the storage of your mobile device as much as possible.
The block header includes its hash, the hash of the previous block, transaction hashes, and additional service information.
Block headers in the Tkeycoin network=84 bytes due to the extension of parameters to support nChains, which will soon be launched in “combat” mode. The titles of the Bitcoin block, Dash, Litecoin=80 bytes.

https://preview.redd.it/uvv3qz7wrtx41.png?width=1230&format=png&auto=webp&s=5cf0cd8b6d099268f3d941aac322af05e781193c
And so, let’s continue — application nodes receive information from the blockchain by uploading block headers, all data is synchronized using the Merkle Tree, or rather your node receives and validates information from the Merkle root.
The hash tree was developed in 1979 by Ralph Merkle and named in his honor. The structure of the system has received this name also because it resembles a tree.
The Merkle tree is a complete binary tree with leaf vertexes containing hashes from data blocks, and inner vertexes containing hashes from adding values in child vertexes. The root node of the tree contains a hash from the entire data set, meaning the hash tree is a unidirectional hash function. The Merkle tree is used for the efficient storage of transactions in the cryptocurrency blockchain. It allows you to get a “fingerprint” of all transactions in the block, as well as effectively verify transactions.

https://preview.redd.it/3hmbthpxrtx41.png?width=677&format=png&auto=webp&s=cca3d54c585747e0431c6c4de6eec7ff7e3b2f4d
Hash trees have an advantage over hash chains or hash functions. When using hash trees, it is much less expensive to prove that a certain block of data belongs to a set. Since different blocks are often independent data, such as transactions or parts of files, we are interested in being able to check only one block without recalculating the hashes for the other nodes in the tree.
https://i.redd.it/f7o3dh7zrtx41.gif
The Merkle Tree scheme allows you to check whether the hash value of a particular transaction is included in Merkle Root, without having all the other transactions in the block. So by having the transaction, block header, and Merkle Branch for that transaction requested from the full node, the digital wallet can make sure that the transaction was confirmed in a specific block.

https://i.redd.it/88sz13w0stx41.gif
The Merkle tree, which is used to prove that a transaction is included in a block, is also very well scaled. Because each new “layer” added to the tree doubles the total number of “leaves” it can represent. You don’t need a deep tree to compactly prove transaction inclusion, even among blocks with millions of transactions.

Statistical constants and nChains

To support the Tkeycoin cryptocurrency, the TkeySpace application uses additional statistical constants to prevent serialization of Merkle tree hashes, which provides an additional layer of security.
Also, for Tkeycoin, support for multi-chains (nChains) is already included in the TkeySpace app, which will allow you to use the app in the future with most of the features of the TKEY Protocol, including instant transactions.

The Bloom Filter

An additional level of privacy is provided by the bloom filter — which is a probabilistic data structure that allows you to check whether an element belongs to a set.

https://preview.redd.it/7ejkvi82stx41.png?width=374&format=png&auto=webp&s=ed75cd056949fc3a2bcf48b4d7ea78d3dc6d81f3
The bloom filter looks for whether a particular transaction is linked to Alice, not whether Alice has a specific cryptocurrency. In this way, transactions and received IDs are analyzed through a bloom filter. When “Alice wants to know about transaction X”, an ID is requested for transaction X, which is compared with the filled segments in her bloom filter. If “Yes” is received, the node can get the information and verify the transaction.

https://preview.redd.it/gjpsbss3stx41.png?width=1093&format=png&auto=webp&s=4cdcbc827849d13b7d6f0b7e7ba52e65ddc03a82

HD support

The multi-currency wallet TkeySpace is based on HD (or hierarchical determinism), a privacy-oriented method for generating and managing addresses. Each wallet address is generated from an xPub wallet (or extended public key). The app is completely anonymous — and individual address is generated for each transaction to accept a particular cryptocurrency. Even for low-level programming, using the same address is negative for the system, not to mention your privacy. We recommend that you always use a new address for transactions to ensure the necessary level of privacy and security.
The EXT_PUBLIC_KEY and EXT_SECRET_KEY values for DASH, Bitcoin, and Litecoin are completely identical. Tkeycoin uses its values, as well as other methods for storing transactions and blocks (RDBMS), and of course — nChains.

Secret key

Wallets in the blockchain have public and private keys.
https://preview.redd.it/br9kk8n5stx41.png?width=840&format=png&auto=webp&s=a36e4c619451735469a9cff57654d322467e4fba
Centralized applications usually store users’ private keys on their servers, which makes users’ funds vulnerable to hacker attacks or theft.
A private key is a special combination of characters that provides access to cryptocurrencies stored on the account. Only a person who knows the key can move and spend digital assets.
TkeySpace — stores the encrypted key only on the user’s device and in encrypted form. The encrypted key is displayed as a mnemonic phrase (backup phrase), which is very convenient for users. Unlike complex cryptographic ciphers, the phrase is easy to save or write. A backup keyword provides the maximum level of security.
A mnemonic phrase is 12 or 24 words that are generated using random number entropy. If a phrase consists of 12 words, then the number of possible combinations is 204⁸¹² or 21¹³² — the phrase will have 132 security bits. To restore the wallet, you must enter the mnemonic phrase in strict order, as it was presented after generation.

Result

Now we understand that your application TkeySpace is a node of the blockchain that communicates with other nodes using p2p messages, stores block headers and validate information using the Merkle Tree, verifies transactions, filters information using the bloom filter, and operates completely in a decentralized model. The application code contains all the necessary blockchain settings for communicating with the network, the so-called chain parameters.
TkeySpace is a new generation mobile app. A completely new level of security, easy user-friendly interfaces and all the necessary features that are required to work with cryptocurrency.

Plasma Update March 26, 2019

The past two weeks have largely been spent on closing out a bunch of feature work as well as some clean up. For the feature work, we’ve finished up development on:
During this validation phase of our internal alpha testnet, we’ve learned a lot about how the system runs over a longer period of time. We’ve run into some availability issues related to syncing with geth, the first Ethereum client we integrated with. We’ve spent a lot of effort refactoring the services to be more fault tolerant of geth crashes and have continued to improve syncing. Additionally, in the interest of consistent availability, we’ve added parity support for our services so that we can work towards redundancy in case one node fails.* In pursuit of our commitment to providing our integrators and partners a reliable service, we’ll be continuing this resiliency and availability work in the upcoming iterations.

*For those who are not familiar, geth and parity are the two leading Ethereum clients, which allow users to interact with the Ethereum chain. Different clients are often written in different languages and offer different features; building for multiple clients means extra work but provides greater resiliency in case one client has issues.

Notes

Video starts at [4:36].

[4:56] 1. Testing Updates

No updates.

[5:27] 2. Yellow paper update.

Gavin put the Yellow Paper under the Creative Commons Free Culture License CC-BY-SA. Yoichi and Nick Savers have been making progress handling the Yellow Paper PRs. There is still the somewhat unresolved issue of what should define the "formal standard" of Ethereum and should an update to the Yellow Paper or another specification be required for every new EIP. This can be discussed in more detail in future meetings when there is greater attendance.

[7:43] 3. EWASM update + update on the following related EIPs.

[7:55] General update

Ewasm contributors are currently meeting in person together in Lisbon. EWASM EIPs listed in the subpoints are not up to date and can be disregarded. People should use the github.com/EWASM/design repo. The design has been pretty much speced out in the last year. During the design phase there were 2 implementations done in parallel: Javascript and C++ (which can be integrated in cpp-ethereum and geth). Issues have been faced in building out EWASM including struggling with implementing synchronous code in Javascript/browser. Idea was to move to an asynchronous model. Currently there is not a full decision on using synchronous vs asynchronous, but we are leaning towards synchronous implementation in C++ to run a testnet in cpp-ethereum that can run pure Web Assembly contracts. Metering contract in Web Assembly is on the to-do list and doesn't rely on sync/async decision. Likely will take week to come to a decision on sync vs async. More technical discussion and a funny anecdote involving the asynchronous vs synchronous decision and the affects of the recent Spectre/Meltdown attacks start at [12:07].

[15:08] a. EVM 2.0 - https://github.com/ethereum/EIPs/issues/48

Martin Becze will be closing this EIP. It is outdated.

[15:28] b. Extend DUP1-16 / SWAP1-16 With DUPN / SWAPN - https://github.com/ethereum/EIPs/issues/174

This doesn't have to do with EWASM, it has to do with adding extra opcodes in the current EVM. It is an upgrade to EVM 1.0 which is not needed if we skip straight to EWASM.

[16:47] c. Subroutines and Static Jumps for the EVM - https://github.com/ethereum/EIPs/issues/615

Greg has been working with Seed (Gitter tag) who is writing an ELM formalization of the EIP. Greg says that there is no formal social process for deciding things like EVM 1.5 implementation so he is not sure if/when it would be implemented. Greg has been working on cleaning up the proposal for those who want to use it. Greg has some ideas around an EVM 3.0 that pulls everything together with transpilation that he hasn't started working on yet and is not sure if he will.

[20:14] 4. Stateless client development.

Piper left some comments about some development of a stateless client for sharding, but it is very early. Alexey had a blog post describing stateless clients he may re-approach later.

[21:46] 5. Add ECADD and ECMUL pre-compiles for secp256k1 - https://github.com/ethereum/EIPs/issues/603 [See this blog post for context].

This topic was brought up months ago with mixed commentary. Christian R. says that ECADD and ECMUL were never intended to be used for general purpose cryptography, but rather it was suppose to be used in conjunction with the pairing pre-compiles for a specific curve that is pairing friendly. Christian says that in the past it has been discussed that there must be a very compelling reason for adding a pre-compile to Ethereum. Silur mentioned that the Monero research team is working on a new ring signature (still unnamed) that can be viewed in the Monero repository. The EWASM team may run some tests to compare native running of the pre-compiles vs EWASM. Adding a new pre-compile would only give a constant speed-up or reduction in cost, but if we achieve the same thing in new virtual machine it will give us a constant speed-up for every conceivable routine and allows for building other schemes like Casper and TrueBit. This is easier with Web Assembly because we can use existing C code. For the moment it looks like focusing energy on adding these proposed pre-compiles would not be worth it compared to just waiting for the next VM (likely EWASM) which will allow far more speed-ups across all computational routines.

[37:00] 6. Introduce miner heuristic "Child pays for parent" (like in BTC) to combat the weird cases when transactions with 1000 Gwei stuck in the mempool (because they are dependent via nonce on transaction paying much less and not getting mined).

[Note: I tried my best to cover what was discussed here, but I am not an expert in Ethereum transactions. If you find a mistake please point it out to me. Thanks!] Agenda item brought up to get people's opinion on this topic. Currently in Ethereum there are transactions that are stuck in the mempool for a long time because of the way transaction ordering per account is handled. The nonce of a transaction must be greater than the previous mined transactions (or equal if you are trying to replace a transaction). For example you can't process transaction #27 before transaction #26 has been mined. Many of the stuck transactions are dependent on other transactions that pay a much smaller fee, but are not being mined. It seems people inadvertently send an initial transaction with too small of a fee and then more transactions at a higher nonce with a much higher fee that cannot be processed until the first small fee transaction is processed. Alexey wondered if this may pose an attack vector or if we would get a benefit from implementing "child pays for parent" like Bitcoin does. Peter explained even if you define the max amount of gas your transaction could potentially consume, there is no guarantee it will use that much and we won't know until the transaction is processed (the only guarantee is that 21,000 gas will be consumed - a plain ether transfer). The attack vector example would be someone pushing a transaction that truly consumes 3,000,000 gas and attach a transaction fee of 1 wei and then push another TX that claims to consume 3,000,000 gas but with a transaction fee of 1000gwei. From the outside it looks like I can both can be executed for profit from the miner's perspective, but in reality the 2nd transaction will be processed first and the 1st tx will be long running and indirectly punish the miner. Alexey was concerned about the mempool filling up and impact on clients due to the way nonces are handled. Peter clarified that transactions in the mempool in the go ethereum client only maintains the top 4,000 most expensive transactions. If your cheap transaction gets evicted, the expensive transactions you stacked on top of it get evicted as well because they are no longer executable due to the nonce.

[42:21] 7. Creating a relay network of nodes to mitigate issues described here and other transaction propagation issues.

A relay network in general is a group of peers and/or miners who use a peer list to quickly connect to a group of known peers before connecting to (or instead of connecting to) random peers using network discovery. Alexey conjectured that this may create a powerful ring of network players who can share transactions very quickly and hurt the little guys on the outside (hurting the idea of this being a mesh network of peers). Clarifications were made about the issues involving transaction propagation issues with nodes with high transaction throughput such as Infura and Bittrex. Clients suddenly stop pushing transactions or cannot keep up with the blockchain when they are pushing out so many transactions. Hudson will work towards exploring this issue more and connecting the people with the issues with the devs.

[49:45] 8. Fork release management/Constantinople.

Hudson will be working on writing up a starting plan to discuss potential release management issues. BitsBeTripping sent Hudson some good material about project management that he will review and bring to the next meeting. We need to start discussing Constantinople sooner rather than later.

[52:55] 9. Client updates.

10. Other non-agenda items

[1:05:42] Question: Will we see any scaling improvements from Constantinople?

Answer is no because it potentially includes the first steps of the Casper consensus protocol and some account abstraction EIPs, but both of those do not alleviate scaling issues. Sharding would alleviate some of the issues. We are currently mostly bound by database and processing speed due to the database. Short term there are a lot of client improvements that can be accomplished to improve disk I/O, but long term things like sharding will be necessary. The Eth Research site has a lot of interesting threads about sharding including merkle tree formats to be used and ideas around asynchronous accumulators

[1:09:57] Decision process for EIPs?

Needs to be improved. Hudson and others will work on updating EIP #1 and other improvements in Q1. Nick Savers has been added as an EIP editor. Yoichi has been added as an editor. Both are doing a great job.

Decred Journal – September 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link).

Development

Final version 1.3.0 of the core software was released bringing all the enhancements reported last month to the rest of the community. The groundwork for SPV (simplified payment verification) is complete, another reduction of fees is being deployed, and performance stepped up once again with a 50% reduction in startup time, 20% increased sync speed and more than 3x faster peer delivery of block headers (a key update for SPV). Decrediton's integrations of SPV and Politeia are open for testing by experienced users. Read the full release notes and get the downloads on GitHub. As always, don't forget to verify signatures.
dcrd: completed several steps towards multipeer downloads, improved introduction to the software in the main README, continued porting cleanups and refactoring from upstream btcd.
Currently in review are initial release of smart fee estimator and a change to UTXO set semantics. The latter is a large and important change that provides simpler handling, and resolves various issues with the previous approach. A lot of testing and careful review is needed so help is welcome.
Educational series for new Decred developers by @matheusd added two episodes: 02 Simnet Setup shows how to automate simnet management with tmux and 03 Miner Reward Invalidation explains block validity rules.
Finally, a pull request template with a list of checks was added to help guide the contributors to dcrd.
dcrwallet: bugfixes and RPC improvements to support desktop and mobile wallets.
Developers are welcome to comment on this idea to derive stakepool keys from the HD wallet seed. This would eliminate the need to backup and restore redeem scripts, thus greatly improving wallet UX. (missed in July issue)
Decrediton: bugfixes, refactoring to make the sync process more robust, new loading animations, design polishing.
Politeia: multiple improvements to the CLI client (security conscious users with more funds at risk might prefer CLI) and security hardening. A feature to deprecate or timeout proposals was identified as necessary for initial release and the work started. A privacy enhancement to not leak metadata of ticket holders was merged.
Android: update from @collins: "Second test release for dcrandroid is out. Major bugs have been fixed since last test. Latest code from SPV sync has been integrated. Once again, bug reports are welcome and issues can be opened on GitHub". Ask in #dev room for the APK to join testing.
A new security page was added that allows one to validate addresses and to sign/verify messages, similar to Decrediton's Security Center. Work on translations is beginning.
Overall the app is quite stable and accepting more testers. Next milestone is getting the test app on the app store.
iOS: the app started accepting testers last week. @macsleven: "the test version of Decred Wallet for iOS is available, we have a link for installing the app but the builds currently require your UDID. Contact either @macsleven or @raedah with your UDID if you would like to help test.".
Nearest goal is to make the app crash free.
Both mobile apps received new design themes.
dcrdata: v3.0 was released for mainnet! Highlights: charts, "merged debits" view, agendas page, Insight API support, side chain tracking, Go 1.11 support with module builds, numerous backend improvements. Full release notes here. This release featured 9 contributors and development lead @chappjc noted: "This collaboration with @raedahgroup on our own block explorer and web API for @decredproject has been super productive.".
Up next is supporting dynamic page widths site wide and deploying new visual blocks home page.
Trezor: proof of concept implementation for Trezor Model T firmware is in the works (previous work was for Model One).
Ticket splitting: updated to use Go modules and added simnet support, several fixes.
docs: beginner's guide overhaul, multiple fixes and cleanups.
decred.org: added 3rd party wallets, removed inactive PoW pools and removed web wallet.
@Richard-Red is building a curated list of Decred-related GitHub repositories.
Welcome to new people contributing for the first time: @klebe, @s_ben, @victorguedes, and PrimeDominus!
Dev activity stats for September: 219 active PRs, 197 commits, 28.7k added and 18.8k deleted lines spread across 6 repositories. Contributions came from 4-10 developers per repository. (chart)

Network

Hashrate: started and ended the month around 75 PH/s, hitting a low of 60.5 and a new high of 110 PH/s. BeePool is again the leader with their share varying between 23-54%, followed by F2Pool 13-30%, Coinmine 4-6% and Luxor 3-5%. As in previous months, there were multiple spikes of unidentified hashrate.
Staking: 30-day average ticket price is 98 DCR (+2.4). The price varied between 95.7 and 101.9 DCR. Locked DCR amount was 3.86-3.96 million DCR, or 45.7-46.5% of the supply.
Nodes: there are 201 public listening nodes and 325 normal nodes per dcred.eu. Version distribution: 5% are v1.4.0(pre) dev builds (+3%), 30% on v1.3.0 (+25%), 42% on v1.2.0 (-20%), 15% on v1.1.2 (-7%), 6% on v1.1.0. More than 76% of nodes run v1.2.0 and higher and therefore support client filters. Data as of Oct 1.

ASICs

Obelisk posted two updates on their mailing list. 70% of Batch 1 units are shipped, an extensive user guide is available, Obelisk Scanner application was released that allows one to automatically update firmware. First firmware update was released and bumped SC1 hashrate by 10-20%, added new pools and fixed multiple bugs. Next update will focus on DCR1. It is worth a special mention that the firmware source code is now open! Let us hope more manufacturers will follow this example.
A few details about Whatsminer surfaced this month. The manufacturer is MicroBT, also known as Bitwei and commonly misspelled as Bitewei. Pangolinminer is a reseller, and the model name is Whatsminer D1.
Bitmain has finally entered Decred ASIC space with their Antminer DR3. Hash rate is 7.8 TH/s while pulling 1410 W, at the price of $673. These specs mean it has the best GH/W and GH/USD of currently sold miners until the Whatsminer or others come out, although its GH/USD of 11.6 already competes with Whatsminer's 10.5. Discussed on Reddit and bitcointalk, unboxing video here.

Integrations

Meet our 17th voting service provider: decredvoting.com. It is operated by @david, has 2% fee and supports ticket splitting. Reddit thread is here.
For a historical note, the first VSP to support ticket splitting was decredbrasil.com:
@matheusd started tests on testnet several months ago. I contacted him so we could integrate with the pool in June this year. We set up the machine in July and bought the first split ticket on mainnet, using the decredbrasil pool, on July 19. It was voted on July 30. After this first vote on mainnet, we opened the tests to selected users (with more technical background) on the pool. In August we opened the tests to everyone, and would call people who want to join to the #ticket_splitting channel, or to our own Slack (in Portuguese, so mostly Brazilian users). We have 28 split tickets already voted, and 16 are live. So little more than 40 split tickets total were bought on decredbrasil pool. (@girino in #pos-voting)
KuCoin exchange listed DCBTC and DCETH pairs. To celebrate their anniversary they had a 99% trading fees discount on DCR pairs for 2 weeks.
Three more wallets integrated Decred in September:
ChangeNow announced Decred addition to their Android app that allows accountless swaps between 150+ assets.
Coinbase launched informational asset pages for top 50 coins by market cap, including Decred. First the pages started showing in the Coinbase app for a small group of testers, and later the web price dashboard went live.

Marketing

Advertising report for September is ready. Next month the graphics for all the ads will be changing.
Marketing might seem quiet right now, but a ton is actually going on behind the scenes to put the right foundation in place for the future. Discovery data are being analyzed to generate a positioning strategy, as well as a messaging hierarchy that can guide how to talk about Decred. This will all be agreed upon via consensus of the community in the work channels, and materials will be distributed.
Next, work is being done to identify the right PR partner to help with media relations, media training, and coordination at events. While all of this is coming up to speed, we believe the website needs a refresher reflecting the soon to be agreed upon messaging, plus a more intuitive architecture to make it easier to navigate.

Large self-posts hang when opening

Hey everyone. This is the second time I've ran into this bug and decided to share. On extremely large self-posts the app hangs for a second before it opens to the post -- whether you tap or 3D Touch it.
On 2.8 beta, iOS 10.1.1, iPhone 6s+
Also, as I'm making this post another bug popped up. When a post (and maybe a comment too?) contains an extremely large amount of text, the input window eventually slows to a crawl making it impossible to continue writing.
Copy pasted the Reddit Wikipedia page to make this post a living example.
In June 2005,[72] Reddit was founded in Medford, Massachusetts by Steve Huffman and Alexis Ohanian, both 22-year-old graduates of the University of Virginia.[73] The team expanded to include Christopher Slowe in November 2005. Between November 2005 and January 2006 Reddit merged with Aaron Swartz's company Infogami, and Swartz became an equal owner of the resulting parent company, Not A Bug.[74][75] Condé Nast Publications, owner of Wired, acquired Reddit on October 31, 2006, and the team moved to San Francisco.[76] In January 2007, Swartz was fired.[77]
By the end of 2008, the team had grown to include Erik Martin, Jeremy Edberg,[78] David King,[79] and Mike Schiraldi.[80] In 2009, Huffman and Ohanian moved on to form Hipmunk, recruiting Slowe[81] and King[82] shortly thereafter. In May 2010, Reddit was named in Lead411's "2010 Hottest San Francisco Companies" list.[83] In July 2010, after explosive traffic growth, Reddit introduced Reddit Gold, offering new features for a price of $3.99/month or $29.99/year.[84] Reddit Gold adds a number of features to the interface, including the ability to display more comments on a page, access to the private "lounge" subreddit, and notifications whenever one's username is mentioned in a comment. It's also possible to endow comments or submissions of other users and thereby give a gold membership to them as an anonymous present.[85]
On September 6, 2011, Reddit became operationally independent of Condé Nast, now operating as a separate subsidiary of its parent company, Advance Publications.[86] On January 11, 2012, Reddit announced that it would be participating in a 12-hour sitewide blackout in protest of the Stop Online Piracy Act.[87] The blackout occurred on January 18 and coincided with the blackouts of Wikipedia and several other websites. In May 2012, Reddit joined the Internet Defense League, a group formed to organize future protests.[88] On February 14, 2013, Reddit began accepting the digital currency bitcoin for its Reddit Gold subscription service through a partnership with bitcoin payment processor Coinbase.[89]
In October 2014, Reddit announced Redditmade, a service which allowed moderators to create merchandise for their subreddits. Redditmade closed in February 2015.[90] In November 2014, Chief Executive Yishan Wong resigned and co-founder Ohanian returned as the full-time executive chairman. Ellen Pao, Reddit's business and partnerships strategist became the interim chief executive.[91] On July 10, 2015, Pao resigned and was replaced by Steve Huffman as CEO.[92][93]
In October 2015, Reddit announced a news portal called Upvoted, designed to broaden the reach of Reddit as a standalone site featuring editorial content from Reddit users.[94] In April 2016, Reddit launched a new blocking tool in an attempt to curb online harassment. The tool allows a user to hide posts and comments from selected redditors in addition to blocking private messages from those redditors.[95] The option to block a redditor is done by clicking a button in the inbox.
Technology
Reddit was originally written in Common Lisp but was rewritten in Python in December 2005.[4] The reasons given for the switch were wider access to code libraries and greater development flexibility. The Python web framework that former Reddit employee Swartz developed to run the site, web.py, is now available as an open-source project.[96] On June 18, 2008, Reddit became an open source project.[97] With the exception of the anti-spam/cheating portions, all of the code and libraries written for Reddit became freely available on GitHub.[98] As of November 10, 2009, Reddit uses Pylons as its web framework.[99]
As of November 10, 2009, Reddit has decommissioned their physical servers and migrated to Amazon Web Services.[100] Reddit uses PostgreSQL as their primary datastore and is slowly moving to Apache Cassandra, a column-oriented datastore. It uses RabbitMQ for offline processing, HAProxy for load balancing and memcached for caching. In early 2009, Reddit started using jQuery.[101] On June 7, 2010, Reddit staff launched a revamped mobile interface featuring rewritten CSS, a new color scheme, and a multitude of improvements.[102]
On July 21, 2010, Reddit outsourced the Reddit search engine to Flaptor, who used its search product IndexTank.[103] As of July 12, 2012, Reddit uses Amazon CloudSearch.[104] There are several unofficial applications that use the Reddit API in the Google Play store, and F-Droid repository. Examples include: Reddit is Fun,[105] Andreddit,[106] F5, BaconReader,[107] Reddit Sync[108] and an Android tablet specific application called Reddita.[109] There are also several Windows apps used to access Reddit, including unofficial Reddit apps such as ReddHub[110] and Reddit To Go!.[111] An unofficial desktop application Reditr[112] exists that is compatible with Windows, OS X, Linux and ChromeOS.
There are several Reddit applications for iOS. These include Karma, Upvote, iReddit, iPad-specific applications such as Reddzine and Biscuit, and, until April 2016, Alien Blue.[113] In September 2014, an official mobile application for browsing AMA (Ask Me Anything) threads was released for the iOS and Android platforms under the name Ask me Anything.[114] In October 2014, Alien Blue was acquired by Reddit and became the official iOS Reddit app.[115] In April 2016, Reddit released an official application called Reddit: The Official App, which is available on Google Play and the iOS App Store, and Alien Blue was removed from the App Store in favor of the new app.[116]
The website is known for its open nature and diverse user community that generate its content.[119] Its demographics allows for wide-ranging subject areas, or main subreddits, that receive much attention, as well as the ability for smaller subreddits to serve more niche purposes. For example, the University of Reddit, a subreddit that exists to communally teach, emerged from the ability to enter and leave the online forum, the "classroom", at will, and classes ranging from computer science to music, to fine art theory exist.[120] The unique possibilities that subreddits provide create new opportunities for raising attention and fostering discussion across many areas. In gaining popularity in terms of unique users per day, Reddit has been a platform for many to raise publicity for a number of causes. And with that increased ability to garner attention and a large audience, users can use one of the largest communities on the Internet for new, revolutionary, and influential purposes.[121]
Its popularity has enabled users to take unprecedented advantage of such a large community. Its innovative socially ranked rating and sorting system drives a method that is useful for fulfilling certain goals of viewership or simply finding answers to interesting questions. User sentiments about the website's function and structure include feelings about the breadth and depth of the discussions on Reddit and how the site makes it easy to discover new and interesting items. Almost all of the user reviews on Alexa.com, which rates Reddit's monthly unique traffic rating 125th in the United States, mention Reddit's "good content" as a likable quality. However, others raise the negative aspects of the potential for Reddit's communities to possess a "hive mind" of sorts,[122] embodying some negative aspects of group interaction theories like crowd psychology and collective consciousness.
Philanthropic efforts Reddit has been known as the instigator of several charity projects, some short and others long-term, in order to benefit others. A selection of major events are outlined below:
In early October 2010, a story was posted on Reddit about a seven-year-old girl, Kathleen Edward, who was in the advanced stages of Huntington's disease. The girl's neighbors were taunting her and her family. Redditors banded together and gave the girl a shopping spree[123][124] at Tree Town Toys, a toy store local to the story owned by a Reddit user. In early December 2010, members of the Christianity subreddit decided to hold a fundraiser[125] and later members of the atheism subreddit decided to give some friendly competition,[126] cross-promoting[127] fundraising drives for Doctors Without Borders and World Vision's Clean Water Fund, respectively. Later, the Islam subreddit joined in, raising money for Islamic Relief. In less than a week, the three communities (as well as the Reddit community at large) raised over $50,000.[128] Most of this was raised by the atheism subreddit, though the smaller Christianity subreddit had a higher average donation amount per subscriber.[129] A similar donation drive in 2011 saw the atheism subreddit raise over $200,000 for charity.[130] Reddit started the largest Secret Santa program in the world, which is still in operation to date. For the 2010 Holiday season, 92 countries were involved in the Secret Santa program. There were 17,543 participants, and $662,907.60 was collectively spent on gift purchases and shipping costs.[131][132][133] In 2014, about 200,000 users from 188 countries participated.[134] Several Celebrities have participated in the program, including Bill Gates[135] and Snoop Dogg.[136] Eventually, the Secret Santa program expanded to various other occasions through Redditgifts. Members from Reddit donated over $600,000 to DonorsChoose in support of Stephen Colbert's March to Keep Fear Alive. The donation spree broke previous records for the most money donated to a single cause by the Reddit community and resulted in an interview with Colbert on Reddit.[137] Reddit users donated $185,356 to Direct Relief for Haiti after an earthquake devastated the nation in January 2010.[138] Reddit users donated over $70,000 to the Faraja Orphanage in the first 24 hours to help secure the orphanage after intruders robbed and attacked one of the volunteers, who survived a strike to the head from a machete.[139] In October 2012, "Shitty Watercolour", a popular Redditor known for posting watercolor paintings on the website,[140][141][142] streamed live a 12-hour painting session on YouTube to raise money for charity: water, a non-profit organization which aims to provide potable drinking water in developing countries. Redditors donated a minimum of $10 to have a photo of their choice painted in a 5 by 5 centimetres (2.0 by 2.0 in) square section of large sheets of paper.[143][144] The paint-a-thon raised $2,700.[145] In February 2014, Reddit announced it would be donating 10% of its annual ad revenue to non-profits voted upon by its users.[146] Reddit continued this policy for 2015, donating $82,765 each to Electronic Frontier Foundation, Planned Parenthood Federation of America, Doctors Without Borders, Erowid Center, Wikimedia Foundation, Multidisciplinary Association for Psychedelic Studies, NPR, Free Software Foundation, Freedom From Religion Foundation, and Tor Project.[147] In response to the 2015 Nepal Earthquake, redditors raised more than $145,000 for Direct Relief and more than $110,000 for MAP International.[148] Commercial activity In February 2013, Betabeat published a post that recognized the influx of multi-national corporations like Costco, Taco Bell, Subaru, and McDonald's posting branded content on Reddit that was made to appear as if it was original content from legitimate Reddit users.[149] Reddit's former Director of Communications noted that while a large number of Chief Marketing Officers want to "infiltrate the reddit community on behalf of their brand," she emphasized that "self-promotion is frowned upon" and the site is "100 percent organic."[150][151][152][153] She recommended that advertisers design promotions that "spark conversations and feedback."[154] She recommended that businesses use AMAs to get attention for public figures but cautioned "It is important to approach AMAs carefully and be aware that this may not be a fit for every project or client."[155] Nissan ran a successful Branded content promotion offering users free gifts to publicize a new car,[156][157] though the company was later ridiculed for suspected astroturfing when the CEO only answered puff piece questions on the site.[158][159] Taylor described these situations as "high risk" noting "We try hard to educate people that they have to treat questions that may seem irreverent or out of left field the same as they would questions about the specific project they are promoting."[160]
Reddit's users are more privacy-conscious than on other websites, using tools like AdBlock and proxies,[161] and they hate "feeling manipulated by brands" but respond well to "content that begs for intelligent viewers and participants."[162] Lauren Orsini writes in ReadWrite that "Reddit's huge community is the perfect hype machine for promoting a new movie, a product release, or a lagging political campaign" but "very specific set of etiquette. Redditors don't want to advertise for you, they want to talk to you."[163] Journalists have used the site as a basis for stories, though they are advised by the site's policies to respect that "reddit's communities belong to their members" and to seek proper attribution for people's contributions.[164]
Reddit announced that they would begin using VigLink to redirect affiliate links in June 2016[165]
Reddit effect Main article: Slashdot effect Also known as the "Slashdot effect", the Reddit effect occurs when a smaller website has a high influx of traffic after being linked to on Reddit.[166] It is also called the "Reddit Hug of Death" among the website's users. Because Reddit is such a large site, the traffic is immense and can easily crash smaller sites. In order for users to see crashed websites, several Reddit bots have been created that take a snapshot of the website before large amounts of traffic flood the affected website.
"Restoring Truthiness" campaign As a response to Glenn Beck's August 28, 2010, Restoring Honor rally (heavily promoted by him in his Fox News broadcasts during the summer), in September 2010 Reddit users started a movement to persuade Stephen Colbert to have a counter-rally in Washington, D.C.[167] The movement, which came to be called "Restoring Truthiness", was started by user mrsammercer, in a post where he described waking up from a dream in which Stephen Colbert was holding a satirical rally in D.C.[168] He writes, "This would be the high water mark of American satire. Half a million people pretending to suspend all rational thought in unison. Perfect harmony. It'll feel like San Francisco in the late 60s, only we won't be able to get any acid."
The idea resonated with the Reddit community, which launched a campaign to bring the event to life. Over $600,000[169] was raised for charity to gain the attention of Colbert. The campaign was mentioned on-air several times, and when the Rally to Restore Sanity and/or Fear was held in Washington, D.C. on October 30, 2010, thousands of redditors made the journey.[170]
During a post-rally press conference, Reddit co-founder Ohanian asked, "What role did the Internet campaign play in convincing you to hold this rally?" Jon Stewart responded by saying that, though it was a very nice gesture, the two had already thought of the idea prior and the deposit on using the National Mall was already paid during the summer, so it acted mostly as a "validation of what we were thinking about attempting".[171] In a message to the Reddit community, Colbert later added, "I have no doubt that your efforts to organize and the joy you clearly brought to your part of the story contributed greatly to the turnout and success."[172]
The website generally lets moderators on individual subreddits make editorial decisions about what content to allow, and has a history of permitting some subreddits dedicated to controversial content.[173] Many of the default pages are highly moderated, with the "science" subreddit banning climate change denialism,[174] and the "news" subreddit banning opinion pieces and columns.[175] Reddit has changed its site-wide editorial policies several times, sometimes in reaction to controversies.[176][177][178][179] Reddit has had a history of giving a platform to objectionable but legal content, and in 2011, news media covered the way that jailbait was being shared on the site before the site changed their policies to explicitly ban "suggestive or sexual content featuring minors".[180] Following some controversial incidents of Internet vigilantism, Reddit introduced a strict rule against the publication of non-public personally-identifying information via the site (colloquially known as doxxing). Those who break the rule are subject to a site-wide ban, and their posts and even entire communities may be removed for breaking the rule.
2010 On December 16, 2010, a redditor named Matt posted a link describing how he has donated a kidney, and included a JustGive link to encourage users to give donations to the American Cancer Society.[181] After an initially positive reaction, Reddit users began to become suspicious of Matt's intentions, and suggested that he was keeping the donations for himself. Users telephoned his home and he received death threats. Matt eventually proved that he was genuine by uploading his doctor's records.[182]
2011 On October 18, 2011, an IT manager submitted a post to the subreddit "gameswap" offering Redditors to trade one of 312 codes he had been given for the game Deus Ex: Human Revolution.[183] A group of users obtained his personal details, and began to blackmail him for the codes.[184] The Monday after uploading the post, he received 138 threatening phone calls both at home and at his job, and by the end of the day he had been fired.[185]
2013 Following the 2013 Boston Marathon bombings, Reddit faced criticism after users wrongly identified a number of people as suspects.[186] Notable among misidentified bombing suspects was Sunil Tripathi, a student reported missing before the bombings took place. A body reported to be Sunil's was found in Providence River in Rhode Island on April 25, 2013, according to Rhode Island Health Department. The cause of death was not immediately known, but authorities said they did not suspect foul play.[187] The family later confirmed Tripathi's death was a result of suicide.[188] Reddit general manager Martin later issued an apology for this behavior, criticizing the "online witch hunts and dangerous speculation" that took place on the website.[189] The incident was later referenced in the season 5 episode of the CBS TV series The Good Wife titled "Whack-a-Mole,"[190] as well as The Newsroom.[191][192]
In late October 2013, the moderators of the "politics" subreddit banned a large group of websites. Many were left wing opinion websites, such as Mother Jones, The Huffington Post, Salon, Alternet, Rawstory, The Daily Kos, Truthout, Media Matters, and ThinkProgress as well as some popular progressive blog sites, such as Democratic Underground and Crooks and Liars. They also banned a number of right wing sites—Drudge Report, Breitbart, The Daily Caller, Dailypaul, Power Line, and Reason. Salon reported that "the section's moderators explained in a post on Tuesday, the goal is 'to reduce the number of blogspam submissions and sensationalist titles.' The purge, the moderators explained, is also aimed at sites that provide lots of "bad journalism."[193] The December 2013 list of banned websites has been modified since late October, and sites with original content, such as Mother Jones and The Huffington Post, are allowed.[194] Moderators also banned RT, which moderators stated was due to vote manipulation and spam, though one moderator stated that he wanted RT banned because it is Kremlin backed.[195][196]
2014 In August 2014, photos from the 2014 celebrity photo hack were widely disseminated across the site.[197][198] A dedicated subreddit, "TheFappening," was created for this purpose,[199] and contained links to most if not all of the criminally obtained explicit images.[200][201][202][203][204] Some images of Liz Lee and McKayla Maroney from the leak were identified by redditors and outside commentators as child pornography because the photos were taken when the women were underage.[205] The subreddit was banned on September 6.[206] The scandal led to wider criticisms concerning the website's administration from The Verge and The Daily Dot.[207][208]
Also in August 2014, moderators and administrators censored a sizeable amount of content related to the GamerGate controversy; one thread in the "gaming" subreddit had almost 24,000 comments removed.[209] Multiple subreddits were deleted by administrators for voicing opinions on Zoe Quinn, Anita Sarkeesian, Brianna Wu and similarly important GamerGate controversy figures.[210] The subreddit "ZoeQuinnDiscussion" was banned for violating the Reddit rules.[211] Administrators defended this response when questioned, blaming 4chan for raiding threads and causing harm. This was debated by some redditors.[212] An anonymous subreddit moderator claims he was removed for leaking correspondence between himself and Zoe Quinn.[213] On December 18, 2014, Reddit took the unusual step of banning a subreddit, "SonyGOP," that was being used to distribute hacked Sony files.[214]
2015 After Ellen Pao became CEO, she was initially a target of criticism by users who objected to her lawsuit.[215] Later on June 10, 2015, Reddit shut down the 150,000-subscriber "fatpeoplehate" subreddit and four others citing issues related to harassment.[216] This move was seen as very controversial; some commenters said that the bans went too far, while others said that the bans did not go far enough.[217] One of the latter complaints concerned a subreddit that was "expressing support" for the perpetrator of the Charleston church shooting.[218] Responding to the accusations of "skewed enforcement", Reddit reaffirmed their commitment to free expression and stated that "There are some subreddits with very little viewership that get highlighted repeatedly for their content, but those are a tiny fraction of the content on the site."
On July 2, 2015, Reddit began experiencing a series of blackouts as moderators set popular subreddit communities to private, in an event dubbed "AMAgeddon," a portmanteau of AMA ("ask me anything") and Armageddon. This was done in protest of the recent firing of Victoria Taylor, an administrator who helped organize citizen-led interviews with famous people on the popular "Ask me Anything" subreddit. Organizers of the blackout also expressed resentment about the recent severance of the communication between Reddit and the moderators of subreddits.[219] The blackout intensified on July 3 when former community manager David Croach gave an AMA about being fired. Before deleting his posts, he stated that Ellen Pao dismissed him with one year of health coverage when he had cancer and did not recover quickly enough.[220][221] Following this, a Change.org petition to remove Pao as CEO of Reddit Inc. reached over 200,000 signatures.[222][223][224] Pao posted a response on July 3 as well as an extended version of it on July 6 in which she apologized for bad communication and not delivering on promises. She also apologized on behalf of the other administrators and noted that problems already existed over the past several years.[225][226][227][228] On July 10, Pao resigned as CEO and was replaced by former CEO and co-founder Steve Huffman.[92][229]

Reddit (stylized as reddit, /ˈrɛdɪt/)[5] is an American social news aggregation, web content rating, and discussion website. Reddit's registered community members can submit content, such as text posts or direct links. Registered users can then vote submissions up or down to organize the posts and determine their position on the site's pages. The submissions with the most positive votes appear on the front page or the top of a category. Content entries are organized by areas of interest called "subreddits". The subreddit topics include news, science, gaming, movies, music, books, fitness, food, and image-sharing, among many others. The site's terms of use prohibit behaviors such as harassment, and moderating and limiting harassment has taken substantial resources.[6]
As of 2017, Reddit had 542 million monthly visitors (234 million unique users), ranking #7 most visited web-site in US and #22 in the world.[7] Across 2015, Reddit saw 82.54 billion pageviews, 73.15 million submissions, 725.85 million comments, and 6.89 billion upvotes from its users.[8]
Reddit was founded by University of Virginia roommates Steve Huffman and Alexis Ohanian in 2005. Condé Nast Publications acquired the site in October 2006. Reddit became a direct subsidiary of Condé Nast's parent company, Advance Publications, in September 2011. As of August 2012, Reddit operates as an independent entity, although Advance is still its largest shareholder.[9] Reddit is based in San Francisco, California. In October 2014, Reddit raised $50 million in a funding round led by Sam Altman and including investors Marc Andreessen, Peter Thiel, Ron Conway, Snoop Dogg, and Jared Leto.[10] Their investment saw the company valued at $500 million.[11][12]

Description Site
The site is a collection of entries submitted by its registered users, essentially a bulletin board system. The name "Reddit" is a play-on-words with the phrase "read it", i.e., "I read it on Reddit."[13] The site's content is divided into numerous categories, and 49 such categories, or "default subreddits", are visible on the front page to new users and those who browse the site without logging in to an account. As of May 2016, these include:[14] Category Subreddits Educational News, Science, Space, DataIsBeautiful, TodayILearned, WorldNews Entertainment Creepy, Documentaries, Gaming, ListenToThis, Movies, Music, NoSleep, Sports, Television, Videos Discussion-based AskReddit, AskScience, Books, ExplainLikeImFive, History, IAmA, TwoXChromosomes Humolight-hearted Funny, InternetIsBeautiful, Jokes, NotTheOnion, ShowerThoughts, TIFU, UpliftingNews Image sharing Art, Aww, EarthPorn, Gifs, MildlyInteresting, OldSchoolCool, PhotoshopBattles, Pics Self-improvement DIY, Food, GetMotivated, LifeProTips, PersonalFinance, Philosophy, WritingPrompts Technology Futurology, Gadgets Meta Announcements, Blog
Note: There are over 11,400 active subreddits[15][16][17] with a default set of 50 subreddits as of February 2016. 
When items (links or text posts) are submitted to a subreddit, the users, called "redditors",[18] can vote for or against them (upvote/downvote). Each subreddit has a front page that shows newer submissions that have been rated highly. Redditors can also post comments about the submission, and respond back and forth in a conversation-tree of comments; the comments themselves can also be upvoted and downvoted. The front page of the site itself shows a combination of the highest-rated posts out of all the subreddits a user is subscribed to.
Front-page rank – for both the general front page and for individual subreddits – is determined by the age of the submission, positive ("upvoted") to negative ("downvoted") feedback ratio and the total vote-count.[19] Dozens of submissions cycle through these front pages daily.
The site's logo and its mascot is a line drawing of an alien nicknamed "Snoo". Subreddits often use themed variants of Snoo relevant to the subject.[20]
Although most of the site functions like a bulletin board or message board, each subreddit has the option of having an associated wiki that can provide supplementary material like instructions, recommended reading, or collaboration for real-life events. Users
Registering an account with Reddit is free and does not require an email address to complete. As of June 2015, there were 36 million user accounts.[21] When logged in, Reddit users (known as redditors) have the ability to vote on submissions and comments to increase or decrease their visibility and submit links and comments. Users can also create their own subreddit on a topic of their choosing, and interested users can add it to their frontpage by subscribing to it. For example, as of May 2015, the Wikipedia subreddit – subtitled "the most interesting pages on Wikipedia" – has over 151,000 subscribers.[22] Reddit comments and submissions are occasionally abbreviated and peppered with terms that are understood within (and in many cases also outside) the Reddit community, ranging from OP (for "original poster" – the user who posted the submission being commented upon) to NSFW (for "not safe for work" – indicating the post has graphic or sexually explicit content).[23] Users earn "post karma" and "comment karma" for submitting text posts, link posts, and comments, which accumulate as point values on their user profile. "Post karma" refers to karma points received from text and link posts, while "comment karma" refers to karma points received from comments. Users may also be gifted "Reddit gold" if another user has well received the comment or post, generally due to humorous or high-quality content; this process is known as "gilding." Reddit has also created a system of points called "creddits". Reddit gold "creddits" are like gift certificates: each creddit you have allows you to give one month of Reddit gold to someone else. The points do not lead to a prize as they are meant to stand in as a badge of honor for the user among their peers, although redditors have attempted to redeem their points before.[24]
Reddit also allows submissions that do not link externally. These are called "self posts" or "text submissions". Many discussion-based subreddits allow only text-only submissions such as "AskReddit" – where users are only allowed to pose broad, discussion based questions to the community at large. Self posts previously did not accumulate karma points for the submitter, but as of July, 2016, these text-only posts generate karma.[25] Mister Splashy Pants logo used on November 27, 2007
Reddit communities occasionally coordinate Reddit-external projects such as skewing polls on other websites, such as in 2007 when Greenpeace allowed web users to decide the name of a humpback whale it was tracking. Reddit users voted en masse to name the whale "Mr. Splashy Pants", and Reddit administrators further encouraged this by changing the site logo to a whale during the voting. In December of that year, Mister Splashy Pants was announced as the winner of the competition.[26]
Within the site, redditors commemorate their "cake day" once a year, which is the anniversary of the day the user's account was first created. The "cake day" offers no special benefit, except that a small icon representing a slice of cake appears next to that user's name for 24 hours.[27] Redditors can "friend" one another, which gives a redditor quick access to posting and comments of their friend list. The commenting system and friend system, along with a certain "Reddit ethos" (called reddiquette on Reddit), lend Reddit aspects of a social networking service, though not to the extent of Facebook, Google+, and other websites aimed at providing social networking services. The Reddit community also socializes at meetups held at local parks and bars around the world,[28] and many localized subreddits for local in-person meetings exist. Subreddits
Reddit entries are organized into areas of interest called "subreddits". Originally, the front page was the "main-reddit", and other areas were "subreddits". There is now no longer a single main-reddit. Instead, there are now 50 "default subreddits" dealing with topics such as books, television, and music, and thousands of additional non-default subreddits. The default subreddits are the 50 subreddits which are first recommended to new users to select from to appear on, or via their customizable top menu bars. All new users are initially automatically "subscribed to" the 50 default subreddits, but can then customize their "subscriptions."
Any registered user who has maintained an account for 31 days or more may create a non-default subreddit.[29] There are over 11,400 active total subreddits to peruse,[15][16][17] including the default set of 50 subreddits as of February 2016. The site has a default "Front Page" which contains staff selected popular articles, and also an "All Page" which contains only the very top ranked article/ subreddits as ranked by readers themselves, and which page is accessible via an "All" link at the top of the "Front Page."
In an interview with Memeburn, Reddit GM, Martin noted that the platform's "approach is to give the community moderators or curators as much control as possible so that they can shape and cultivate the type of communities they want".[30] IAmA and AMA
One of the most popular subreddits is IAmA ("I Am A") where a user may post "AMAs" (for "Ask Me Anything"), or similarly "AMAAs" (for "Ask Me Almost/Absolutely Anything") – prompts for others to ask questions about any topic. AMAs are open to all Reddit users, and use the site's comment system for both questions and answers; it is similar to a press conference but online. This subreddit was founded in May 2009.[31] From 2013 to 2015, Victoria Taylor assisted reddit's volunteer community in presenting interviews.[32][33][34]
A number of notable individuals have participated in the IAmA subreddit, including United States President Barack Obama[35][36] (while campaigning for the 2012 election), Dave Grohl,[37] Madonna,[38] Chris Hadfield[39] (who answered questions from the International Space Station), Bill Gates,[40] Ron Paul,[41] Stephen Colbert,[42] Psy, Enya, Arnold Schwarzenegger, Rachel Maddow, Robin Williams,[43] Renée Fleming, M. Shadows, Louis C.K., Roger Federer, Larry King, Philip Zimbardo, Bill Nye,[44] Stan Lee, John Mather, David Copperfield, Michael Moore, Spike Lee, Paul Krugman, Danny Boyle, rapper J. Cole,[45] Al Gore, Roger Ebert, Michael Bolton, Gary Johnson, Lawrence Krauss, Jill Stein, Kevin Rudd, Julie Benz,[46] Amanda Palmer,[47] Tim Ferriss,[48] Gordon Ramsay,[49] Peter Dinklage,[50] Chandra Wickramasinghe,[51] Neil deGrasse Tyson,[52] and Bernie Sanders.[53] Donald Trump (during his 2016 Presidential Campaign) had an AMA on /The Donald subreddit.[54] As of April 2015, Barack Obama's AMA is the highest rated on the site;[55] the increased traffic brought down many parts of the website when the AMA occurred on August 29, 2012.[56]
Celebrities participating in IAmAs have seen both positive and negative responses. Woody Harrelson's[57] AMA was criticized after Harrelson declined to answer questions that were unrelated to the movie Rampart he was promoting.[58] In contrast, rapper Snoop Dogg attracted 1.6 million page views[59] after conducting an AMA that provided several candid responses to the community's questions.[60]
Other than Harrelson's, Bollywood actress Priyanka Chopra's[61] AMA was criticized for evasiveness when she focused on promoting her upcoming album to the detriment of other questions. A particularly well received AMA of 2014 was that of Peter Dinklage,[62] best known for his role as Tyrion Lannister in the HBO drama series Game of Thrones. Redditors attribute the thread's success to the thoroughness of his responses and the fact that he stayed online much longer than he was expected to so he could spend more time with his fans. The actor departed by commenting:
This feels like being interviewed by a hundred thousand news anchors at once! But much friendlier anchors...who seem to know their material...I really appreciate everyone's enthusiasm and questions. I tried to move another engagement to make more time but it's really hard during shoots. I am going to try to answer a few more short ones now. And remember: If you see me on the street and want a photo, ask! It's just weird when your kid asks for directions.[63] 
On July 2, 2015, hundreds of subreddits, including several with over a million subscribers, were set to private by their respective moderators after Reddit's director of talent, Victoria Taylor, was dismissed.[64][65][66][67] Sources close to Reddit cited an increased focus on commercializing AMAs as the most likely reason.[68][69] /science File:American Chemical Society - What Chemists Do - Nathan Allen.webmPlay media Nathan Allen speaks about /science to the American Chemical Society Main article: /science
/science is an Internet forum on Reddit where the community of participants discuss science topics.[70] A popular feature of the forum is "Ask me Anything" (AMA) public discussions.[70] As of 2014, /science attracted 30,000–100,000 visitors per day, making it the largest community-managed science forum and an attractive place to host discussions.[70] April Fools subreddits The Button Main article: The Button (Reddit)
On April Fools' Day 2015, a social experiment was launched in the form of a subreddit called "thebutton". It featured a button and a 60-second countdown timer. User accounts created before that day were eligible to participate. A user could only ever click the button once, or opt not to click it. If a user clicked the button the timer was globally reset to 60 seconds,[71] and the user's "flair" (an icon next to the user's name) changed color. Colors were assigned based on a gradient from purple to red with purple signifying up to 60 seconds and red as low as 0 seconds. The countdown prematurely reached zero several times due to technical problems but eventually expired without further problems on June 5, 2015, after which the subreddit was archived.[72] Robin
On April Fools' Day 2016, a social experiment was launched in the form of a chat widget named Robin. After clicking the "Robin" button, an IRC-like chat window was initially opened with one other redditor and giving a certain time to pick between three options, "Grow," "Stay" and "Abandon".[73] "Grow" would join the chat with another group, "Stay" would close the group chat and create a subreddit with that group as moderators and "Abandon" would close the group chat and everyone goes back to a group of two. History Further information: Timeline of Reddit Co-founder Alexis Ohanian speaking in 2009
In June 2005,[74] Reddit was founded in Medford, Massachusetts by Steve Huffman and Alexis Ohanian, both 22-year-old graduates of the University of Virginia.[75] The team expanded to include Christopher Slowe in November 2005. Between November 2005 and January 2006 Reddit merged with Aaron Swartz's company Infogami, and Swartz became an equal owner of the resulting parent company, Not A Bug.[76][77] Condé Nast Publications, owner of Wired, acquired Reddit on October 31, 2006, and the team moved to San Francisco.[78] In January 2007, Swartz was fired.[79]
By the end of 2008, the team had grown to include Erik Martin, Jeremy Edberg,[80] David King,[81] and Mike Schiraldi.[82] In 2009, Huffman and Ohanian moved on to form Hipmunk, recruiting Slowe[83] and King[84] shortly thereafter. In May 2010, Reddit was named in Lead411's "2010 Hottest San Francisco Companies" list.[85] In July 2010, after explosive traffic growth, Reddit introduced Reddit Gold, offering new features for a price of $3.99/month or $29.99/year.[86] Reddit Gold adds a number of features to the interface, including the ability to display more comments on a page, access to the private "lounge" subreddit, and notifications whenever one's username is mentioned in a comment. It's also possible to endow comments or submissions of other users and thereby give a gold membership to them as an anonymous present.[87]
On September 6, 2011, Reddit became operationally independent of Condé Nast, now operating as a separate subsidiary of its parent company, Advance Publications.[88] On January 11, 2012, Reddit announced that it would be participating in a 12-hour sitewide blackout in protest of the Stop Online Piracy Act.[89] The blackout occurred on January 18 and coincided with the blackouts of Wikipedia and several other websites. In May 2012, Reddit joined the Internet Defense League, a group formed to organize future protests.[90] On February 14, 2013, Reddit began accepting the digital currency bitcoin for its Reddit Gold subscription service through a partnership with bitcoin payment processor Coinbase.[91]
In October 2014, Reddit announced Redditmade, a service which allowed moderators to create merchandise for their subreddits. Redditmade closed in February 2015.[92] In November 2014, Chief Executive Yishan Wong resigned and co-founder Ohanian returned as the full-time executive chairman. Ellen Pao, Reddit's business and partnerships strategist became the interim chief executive.[93] On July 10, 2015, Pao resigned and was replaced by Steve Huffman as CEO.[94][95]
In October 2015, Reddit announced a news portal called Upvoted, designed to broaden the reach of Reddit as a standalone site featuring editorial content from Reddit users.[96] In April 2016, Reddit launched a new blocking tool in an attempt to curb online harassment. The tool allows a user to hide posts and comments from selected redditors in addition to blocking private messages from those redditors.[97] The option to block a redditor is done by clicking a button in the inbox. Technology
Reddit was originally written in Common Lisp but was rewritten in Python in December 2005.[4] The reasons given for the switch were wider access to code libraries and greater development flexibility. The Python web framework that former Reddit employee Swartz developed to run the site, web.py, is now available as an open-source project.[98] On June 18, 2008, Reddit became an open source project.[99] With the exception of the anti-spam/cheating portions, all of the code and libraries written for Reddit became freely available on GitHub.[100] As of November 10, 2009, Reddit uses Pylons as its web framework.[101]
As of November 10, 2009, Reddit has decommissioned their physical servers and migrated to Amazon Web Services.[102] Reddit uses PostgreSQL as their primary datastore and is slowly moving to Apache Cassandra, a column-oriented datastore. It uses RabbitMQ for offline processing, HAProxy for load balancing and memcached for caching. In early 2009, Reddit started using jQuery.[103] On June 7, 2010, Reddit staff launched a revamped mobile interface featuring rewritten CSS, a new color scheme, and a multitude of improvements.[104]
On July 21, 2010, Reddit outsourced the Reddit search engine to Flaptor, who used its search product IndexTank.[105] As of July 12, 2012, Reddit uses Amazon CloudSearch.[106] There are several unofficial applications that use the Reddit API in the Google Play store, and F-Droid repository. Examples include: Reddit is Fun,[107] Andreddit,[108] F5, BaconReader,[109] Reddit Sync[110] and an Android tablet specific application called Reddita.[111] There are also several Windows apps used to access Reddit, including unofficial Reddit apps such as ReddHub[112] and Reddit To Go!.[113] An unofficial desktop application Reditr[114] exists that is compatible with Windows, OS X, Linux and ChromeOS.
There are several Reddit applications for iOS. These include Karma, Upvote, iReddit, iPad-specific applications such as Reddzine and Biscuit, and, until April 2016, Alien Blue.[115] In September 2014, an official mobile application for browsing AMA (Ask Me Anything) threads was released for the iOS and Android platforms under the name Ask me Anything.[116] In October 2014, Alien Blue was acquired by Reddit and became the official iOS Reddit app.[117] In April 2016, Reddit released an official application called Reddit: The Official App, which is available on Google Play and the iOS App Store, and Alien Blue was removed from the App Store in favor of the new app.[118] Demographics
According to Reddit's Audience and Demographics page, as of December 2015, 53% of redditors are male and 54% are from the United States.[119] In 2013, Pewinternet stated that 6% of all American adult Internet users have used Reddit; that males were twice as likely to be redditors as females were; and that Reddit's largest age bracket was between the ages of 18 and 29.[120] As of the end of 2016, Reddit is the only major social media platform that does not have a female majority user base.[121] Community and culture
The website is known for its open nature and diverse user community that generate its content.[122] Its demographics allows for wide-ranging subject areas, or main subreddits, that receive much attention, as well as the ability for smaller subreddits to serve more niche purposes. For example, the University of Reddit, a subreddit that exists to communally teach, emerged from the ability to enter and leave the online forum, the "classroom", at will, and classes ranging from computer science to music, to fine art theory exist.[123] The unique possibilities that subreddits provide create new opportunities for raising attention and fostering discussion across many areas. In gaining popularity in terms of unique users per day, Reddit has been a platform for many to raise publicity for a number of causes. And with that increased ability to garner attention and a large audience, users can use one of the largest communities on the Internet for new, revolutionary, and influential purposes.[124]
Its popularity has enabled users to take unprecedented advantage of such a large community. Its innovative socially ranked rating and sorting system drives a method that is useful for fulfilling certain goals of viewership or simply finding answers to interesting questions. User sentiments about the website's function and structure include feelings about the breadth and depth of the discussions on Reddit and how the site makes it easy to discover new and interesting items. Almost all of the user reviews on Alexa.com, which rates Reddit's monthly unique traffic rating 125th in the United States, mention Reddit's "good content" as a likable quality. However, others raise the negative aspects of the potential for Reddit's communities to possess a "hive mind" of sorts,[125] embodying some negative aspects of group interaction theories like crowd psychology and collective consciousness. Philanthropic efforts
Reddit has been known as the instigator of several charity projects, some short and others long-term, in order to benefit others. A selection of major events are outlined below:
In early October 2010, a story was posted on Reddit about a seven-year-old girl, Kathleen Edward, who was in the advanced stages of Huntington's disease. The girl's neighbors were taunting her and her family. Redditors banded together and gave the girl a shopping spree[126][127] at Tree Town Toys, a toy store local to the story owned by a Reddit user. In early December 2010, members of the Christianity subreddit decided to hold a fundraiser[128] and later members of the atheism subreddit decided to give some friendly competition,[129] cross-promoting[130] fundraising drives for Doctors Without Borders and World Vision's Clean Water Fund, respectively. Later, the Islam subreddit joined in, raising money for Islamic Relief. In less than a week, the three communities (as well as the Reddit community at large) raised over $50,000.[131] Most of this was raised by the atheism subreddit, though the smaller Christianity subreddit had a higher average donation amount per subscriber.[132] A similar donation drive in 2011 saw the atheism subreddit raise over $200,000 for charity.[133] Reddit started the largest Secret Santa program in the world, which is still in operation to date. For the 2010 Holiday season, 92 countries were involved in the Secret Santa program. There were 17,543 participants, and $662,907.60 was collectively spent on gift purchases and shipping costs.[134][135][136] In 2014, about 200,000 users from 188 countries participated.[137] Several celebrities have participated in the program, including Bill Gates[138] and Snoop Dogg.[139] Eventually, the Secret Santa program expanded to various other occasions through Redditgifts. Members from Reddit donated over $600,000 to DonorsChoose in support of Stephen Colbert's March to Keep Fear Alive. The donation spree broke previous records for the most money donated to a single cause by the Reddit community and resulted in an interview with Colbert on Reddit.[140] Reddit users donated $185,356 to Direct Relief for Haiti after an earthquake devastated the nation in January 2010.[141] Reddit users donated over $70,000 to the Faraja Orphanage in the first 24 hours to help secure the orphanage after intruders robbed and attacked one of the volunteers, who survived a strike to the head from a machete.[142] In October 2012, "Shitty Watercolour", a popular Redditor known for posting watercolor paintings on the website,[143][144][145] streamed live a 12-hour painting session on YouTube to raise money for charity: water, a non-profit organization which aims to provide potable drinking water in developing countries. Redditors donated a minimum of $10 to have a photo of their choice painted in a 5 by 5 centimetres (2.0 by 2.0 in) square section of large sheets of paper.[146][147] The paint-a-thon raised $2,700.[148] In February 2014, Reddit announced it would be donating 10% of its annual ad revenue to non-profits voted upon by its users.[149] Reddit continued this policy for 2015, donating $82,765 each to Electronic Frontier Foundation, Planned Parenthood Federation of America, Doctors Without Borders, Erowid Center, Wikimedia Foundation, Multidisciplinary Association for Psychedelic Studies, NPR, Free Software Foundation, Freedom From Religion Foundation, and Tor Project.[150] In response to the 2015 Nepal earthquake, redditors raised more than $145,000 for Direct Relief and more than $110,000 for MAP International.[151] 
Commercial activity
In February 2013, Betabeat published a post that recognized the influx of multi-national corporations like Costco, Taco Bell, Subaru, and McDonald's posting branded content on Reddit that was made to appear as if it was original content from legitimate Reddit users.[152] Reddit's former Director of Communications noted that while a large number of Chief Marketing Officers want to "infiltrate the reddit community on behalf of their brand," she emphasized that "self-promotion is frowned upon" and the site is "100 percent organic."[153][154][155][156] She recommended that advertisers design promotions that "spark conversations and feedback."[157] She recommended that businesses use AMAs to get attention for public figures but cautioned "It is important to approach AMAs carefully and be aware that this may not be a fit for every project or client."[158] Nissan ran a successful Branded content promotion offering users free gifts to publicize a new car,[159][160] though the company was later ridiculed for suspected astroturfing when the CEO only answered puff piece questions on the site.[161][162] Taylor described these situations as "high risk" noting "We try hard to educate people that they have to treat questions that may seem irreverent or out of left field the same as they would questions about the specific project they are promoting."[163]
Reddit's users are more privacy-conscious than on other websites, using tools like AdBlock and proxies,[164] and they hate "feeling manipulated by brands" but respond well to "content that begs for intelligent viewers and participants."[165] Lauren Orsini writes in ReadWrite that "Reddit's huge community is the perfect hype machine for promoting a new movie, a product release, or a lagging political campaign" but "very specific set of etiquette. Redditors don't want to advertise for you, they want to talk to you."[166] Journalists have used the site as a basis for stories, though they are advised by the site's policies to respect that "reddit's communities belong to their members" and to seek proper attribution for people's contributions.[167]
Reddit announced that they would begin using VigLink to redirect affiliate links in June 2016.[168] Reddit effect Main article: Slashdot effect
Also known as the "Slashdot effect", the Reddit effect occurs when a smaller website has a high influx of traffic after being linked to on Reddit.[169] It is also called the "Reddit Hug of Death" among the website's users. Because Reddit is such a large site, the traffic is immense and can easily crash smaller sites. In order for users to see crashed websites, several Reddit bots have been created that take a snapshot of the website before large amounts of traffic flood the affected website. "Restoring Truthiness" campaign
As a response to Glenn Beck's August 28, 2010, Restoring Honor rally (heavily promoted by him in his Fox News broadcasts during the summer), in September 2010 Reddit users started a movement to persuade satirist Stephen Colbert to have a counter-rally in Washington, D.C.[170] The movement, which came to be called "Restoring Truthiness", was started by user mrsammercer, in a post where he described waking up from a dream in which Stephen Colbert was holding a satirical rally in D.C.[171] He writes, "This would be the high water mark of American satire. Half a million people pretending to suspend all rational thought in unison. Perfect harmony. It'll feel like San Francisco in the late 60s, only we won't be able to get any acid."
The idea resonated with the Reddit community, which launched a campaign to bring the event to life. Over $600,000[172] was raised for charity to gain the attention of Colbert. The campaign was mentioned on-air several times, and when the Rally to Restore Sanity and/or Fear was held in Washington, D.C. on October 30, 2010, thousands of redditors made the journey.[173]
During a post-rally press conference, Reddit co-founder Ohanian asked, "What role did the Internet campaign play in convincing you to hold this rally?" Jon Stewart responded by saying that, though it was a very nice gesture, the two had already thought of the idea prior and the deposit on using the National Mall was already paid during the summer, so it acted mostly as a "validation of what we were thinking about attempting".[174] In a message to the Reddit community, Colbert later added, "I have no doubt that your efforts to organize and the joy you clearly brought to your part of the story contributed greatly to the turnout and success."[175] Controversies See also: Controversial Reddit communities and Michael Brutsch
The website generally lets moderators on individual subreddits make editorial decisions about what content to allow, and has a history of permitting some subreddits dedicated to controversial content.[176] Many of the default pages are highly moderated, with the "science" subreddit banning climate change denialism,[177] and the "news" subreddit banning opinion pieces and columns.[178] Reddit has changed its site-wide editorial policies several times, sometimes in reaction to controversies.[179][180][181][182] Reddit has had a history of giving a platform to objectionable but legal content, and in 2011, news media covered the way that jailbait was being shared on the site before the site changed their policies to explicitly ban "suggestive or sexual content featuring minors".[183] Following some controversial incidents of Internet vigilantism, Reddit introduced a strict rule against the publication of non-public personally-identifying information via the site (colloquially known as doxxing). Those who break the rule are subject to a site-wide ban, and their posts and even entire communities may be removed for breaking the rule. 2010
On December 16, 2010, a redditor named Matt posted a link describing how he has donated a kidney, and included a JustGive link to encourage users to give donations to the American Cancer Society.[184] After an initially positive reaction, Reddit users began to become suspicious of Matt's intentions, and suggested that he was keeping the donations for himself. Users telephoned his home and he received death threats. Matt eventually proved that he was genuine by uploading his doctor's records.[185] 2011
On October 18, 2011, an IT manager submitted a post to the subreddit "gameswap" offering Redditors to trade one of 312 codes he had been given for the game Deus Ex: Human Revolution.[186] A group of users obtained his personal details, and began to blackmail him for the codes.[187] The Monday after uploading the post, he received 138 threatening phone calls both at home and at his job, and by the end of the day he had been fired.[188] 2013
Following the 2013 Boston Marathon bombings, Reddit faced criticism after users wrongly identified a number of people as suspects.[189] Notable among misidentified bombing suspects was Sunil Tripathi, a student reported missing before the bombings took place. A body reported to be Sunil's was found in Providence River in Rhode Island on April 25, 2013, according to Rhode Island Health Department. The cause of death was not immediately known, but authorities said they did not suspect foul play.[190] The family later confirmed Tripathi's death was a result of suicide.[191] Reddit general manager Martin later issued an apology for this behavior, criticizing the "online witch hunts and dangerous speculation" that took place on the website.[192] The incident was later referenced in the season 5 episode of the CBS TV series The Good Wife titled "Whack-a-Mole,"[193] as well as The Newsroom.[194][195]
In late October 2013, the moderators of the "politics" subreddit banned a large group of websites. Many were left wing opinion websites, such as Mother Jones, The Huffington Post, Salon, Alternet, Rawstory, The Daily Kos, Truthout, Media Matters, and ThinkProgress as well as some popular progressive blog sites, such as Democratic Underground and Crooks and Liars. They also banned a number of right wing sites—Drudge Report, Breitbart, The Daily Caller, Dailypaul, Power Line, and Reason. Salon reported that "the section's moderators explained in a post on Tuesday, the goal is 'to reduce the number of blogspam submissions and sensationalist titles.' The purge, the moderators explained, is also aimed at sites that provide lots of "bad journalism."[196] The December 2013 list of banned websites has been modified since late October, and sites with original content, such as Mother Jones and The Huffington Post, are allowed.[197] Moderators also banned RT, which moderators stated was due to vote manipulation and spam, though one moderator stated that he wanted RT banned because it is Kremlin backed.[198][199] 2014
In August 2014, photos from the 2014 celebrity photo hack were widely disseminated across the site.[200][201] A dedicated subreddit, "TheFappening," was created for this purpose,[202] and contained links to most if not all of the criminally obtained explicit images.[203][204][205][206][207] Some images of Liz Lee and McKayla Maroney from the leak were identified by redditors and outside commentators as child pornography because the photos were taken when the women were underage.[208] The subreddit was banned on September 6.[209] The scandal led to wider criticisms concerning the website's administration from The Verge and The Daily Dot.[210][211]
Also in August 2014, moderators and administrators censored a sizeable amount of content related to the GamerGate controversy; one thread in the "gaming" subreddit had almost 24,000 comments removed.[212] Multiple subreddits were deleted by administrators for voicing opinions on Zoe Quinn, Anita Sarkeesian, Brianna Wu and similarly important GamerGate controversy figures.[213] The subreddit "ZoeQuinnDiscussion" was banned for violating the Reddit rules.[214] Administrators defended this response when questioned, blaming 4chan for raiding threads and causing harm. This was debated by some redditors.[215] An anonymous subreddit moderator claims he was removed for leaking correspondence between himself and Zoe Quinn.[216] On December 18, 2014, Reddit took the unusual step of banning a subreddit, "SonyGOP," that was being used to distribute hacked Sony files.[217] 2015
After Ellen Pao became CEO, she was initially a target of criticism by users who objected to her lawsuit.[218] Later on June 10, 2015, Reddit shut down the 150,000-subscriber "fatpeoplehate" subreddit and four others citing issues related to harassment.[219] This move was seen as very controversial; some commenters said that the bans went too far, while others said that the bans did not go far enough.[220] One of the latter complaints concerned a subreddit that was "expressing support" for the perpetrator of the Charleston church shooting.[221] Responding to the accusations of "skewed enforcement", Reddit reaffirmed their commitment to free expression and stated that "There are some subreddits with very little viewership that get highlighted repeatedly for their content, but those are a tiny fraction of the content on the site."
On July 2, 2015, Reddit began experiencing a series of blackouts as moderators set popular subreddit communities to private, in an event dubbed "AMAgeddon," a portmanteau of AMA ("ask me anything") and Armageddon. This was done in protest of the recent firing of Victoria Taylor, an administrator who helped organize citizen-led interviews with famous people on the popular "Ask me Anything" subreddit. Organizers of the blackout also expressed resentment about the recent severance of the communication between Reddit and the moderators of subreddits.[222] The blackout intensified on July 3 when former community manager David Croach gave an AMA about being fired. Before deleting his posts, he stated that Ellen Pao dismissed him with one year of health coverage when he had cancer and did not recover quickly enough.[223][224] Following this, a Change.org petition to remove Pao as CEO of Reddit Inc. reached over 200,000 signatures.[225][226][227] Pao posted a response on July 3 as well as an extended version of it on July 6 in which she apologized for bad communication and not delivering on promises. She also apologized on behalf of the other administrators and noted that problems already existed over the past several years.[228][229][230][231] On July 10, Pao resigned as CEO and was replaced by former CEO and co-founder Steve Huffman.[94][232]
