Timeline

Reddit's own transparency reports document persistent spam and inauthentic-account activity. The problem moved from anonymous spammers to credentialed academics in 2025, when University of Zurich researchers secretly ran AI bots posing as real people in r/changemyview to test machine persuasion without users' consent.

In February 2024, days before its IPO, Reddit signed a content-licensing deal with Google reported at roughly $60 million per year, giving Google access via Reddit's Data API to train AI models on years of user content. The deal drew user unease over consent and triggered an FTC inquiry.

When Reddit went public on the NYSE (RDDT) in March 2024, it offered a slice of IPO shares to top moderators and users via a Directed Share Program. Many community members rejected the gesture as cynical, noting the volunteer moderators who built Reddit's value still received no compensation while CEO Steve Huffman earned $193 million in 2023.

In a series of copyright cases, movie distributors subpoenaed Reddit to unmask anonymous users who had commented about piracy, but federal magistrate judges in the Northern District of California repeatedly quashed the subpoenas, holding the First Amendment right to anonymous speech outweighed the studios' need.

After the initial June 2023 API blackout failed to move Reddit, major subreddits including r/pics, r/aww and r/gifs held polls and reopened under a malicious-compliance rule allowing only images of comedian John Oliver. Oliver himself endorsed the stunt and supplied photos.

After the June 2023 API blackout, Reddit invoked its Moderator Code of Conduct to threaten and then remove the mod teams of subreddits that stayed dark, while CEO Steve Huffman dismissed moderators as 'landed gentry.' When protesters marked communities NSFW to strip out ads, Reddit issued final warnings and forced them back to SFW.

Reddit's decision to charge punitive prices for API access killed popular third-party apps like Apollo and triggered the largest protest in the site's history — followed by the removal of protesting moderators.

Section 230 immunizes Reddit, its moderators, and its users from liability for posted content, leaving people defamed on the platform with few options short of costly litigation to unmask anonymous posters.

Reddit runs on unpaid volunteer moderators whose exposure to harmful content and harassment causes documented psychological harm — a problem underscored by professional-moderator PTSD lawsuits across the industry.

After banning the notorious r/jailbait subreddit in 2011, Reddit continued to face documented child sexual abuse material (CSAM) problems through the 2020s, including a 2021 federal lawsuit and sharply rising NCMEC CyberTipline reports as the platform expanded media sharing.

As r/wallstreetbets drove the January 2021 GameStop short squeeze, Discord banned the community's server for repeated hate-speech violations, and days later a group of returning moderators attempted to seize control of the subreddit to cash in on a movie deal, prompting Reddit to remove them.

A handful of 'power moderators' control a disproportionate share of Reddit's biggest communities. The long-running controversy over u/AwkwardTheTurtle became the emblem of the problem.

In late August 2021, moderators of roughly 135 subreddits took their communities private to protest Reddit's refusal to act on COVID-19 misinformation; days later Reddit banned the COVID-denialist hub r/NoNewNormal — citing brigading rather than misinformation — and quarantined 54 other subreddits.

Reddit hired a controversial figure as an administrator, then banned a moderator for linking to reporting about her — sparking a mass subreddit blackout before the company reversed course.

Reddit's largest pro-Trump community was quarantined in 2019 over threats of violence and banned in 2020 as part of a sweeping hate-speech policy update.

After years of warnings and a 2019 quarantine, Reddit banned the pro-Trump subreddit r/The_Donald in June 2020. Its community had already built and migrated to the independent site TheDonald.win (later patriots.win), which reputable reporting and the official January 6th Committee report later tied to violent rhetoric and planning around the 2021 Capitol attack.

On March 15, 2019, within hours of the livestreamed Christchurch mosque shootings, Reddit permanently banned the long-running r/WatchPeopleDie (300,000+ subscribers) and r/gore communities after users shared footage of the attack, citing its policy against glorifying or encouraging violence.

In February 2019 Chinese tech giant Tencent invested $150 million as part of a $300 million Reddit funding round, triggering a site-wide protest in which users flooded Reddit with content banned in China — Tiananmen 'Tank Man' images and Winnie the Pooh — over fears of CCP-aligned censorship. The episode amplified longstanding concerns about coordinated pro-Beijing activity.

On September 27-28, 2018, Reddit formalized and expanded its 'quarantine' mechanism — gating offensive subreddits behind an opt-in warning page, stripping ad revenue, and hiding them from search — then applied it to more than 20 communities including r/CringeAnarchy, r/WatchPeopleDie, r/TheRedPill, and r/Braincels, triggering accusations of censorship and inconsistent enforcement.

On November 7, 2017, Reddit banned the ~40,000-subscriber r/Incels community under a newly updated policy prohibiting content that encourages or glorifies violence. The incel community regrouped on r/Braincels, which Reddit quarantined in September 2018 and banned in late 2019.

In late November 2016, Reddit CEO Steve Huffman (u/spez) used his admin database access to silently rewrite comments from r/The_Donald users who had insulted him, replacing his own username with the names of the subreddit's moderators. He admitted it after users noticed and later issued a formal apology.

Reddit interim CEO Ellen Pao resigned on July 10, 2015, after the surprise firing of popular talent director Victoria Taylor triggered a site-wide moderator revolt, and a petition demanding her ouster drew more than 200,000 signatures amid a torrent of sexist and racist abuse directed at her.

On August 5, 2015, returning CEO Steve Huffman (u/spez) rolled out an updated content policy and banned r/CoonTown along with a cluster of openly racist subreddits, while introducing a new 'quarantine' tier for offensive-but-permitted communities.

On June 10, 2015, Reddit banned r/fatpeoplehate and four other subreddits under an anti-harassment policy first announced in May 2015, triggering a site-wide revolt that flooded r/all and targeted interim CEO Ellen Pao with abuse.

Reddit became a primary hub for the 2014 'Fappening' celebrity nude-photo leaks via the r/TheFappening subreddit, removing it only under DMCA and child-imagery pressure; nearly six months later, on February 24, 2015, Reddit announced a privacy-policy change banning the posting of explicit images of anyone without their consent.

The abrupt firing of AMA coordinator Victoria Taylor triggered a revolt in which moderators of r/IAmA and more than a thousand other subreddits went private in protest.

In the chaos after the 2013 Boston Marathon bombing, Reddit users wrongly named several innocent people as suspects — including Brown University student Sunil Tripathi, who had already died by suicide a month before the attack.

r/CreepShots hosted secretly-taken sexualized photos of women and girls in public without their consent. After a Georgia teacher case and Gawker's October 2012 unmasking of moderator 'Violentacrez' (Michael Brutsch), the subreddit was shut down.

Gawker's Adrian Chen identified Reddit's most notorious moderator, 'Violentacrez', as a 49-year-old Texas programmer — igniting a fierce debate over anonymity, doxxing, and moderator power.

For roughly three years Reddit hosted r/jailbait, a community trading sexualized images of underage girls, before public pressure forced its closure in October 2011.
