Reddit removed the top moderator of r/LiveStreamFail after he used the 4-million-member subreddit to promote 'Million Dollar Fan', a reality show advertising a suspiciously large prize that collapsed amid scam allegations — reviving fears that moderators sell community access.

In May 2026 Reddit began deploying an unskippable full-screen overlay on its mobile website telling users to 'Get the app to keep using Reddit,' with no close or continue-in-browser option — a dark-pattern escalation of years of nag screens that drew immediate backlash.

On 24 February 2026 the UK Information Commissioner's Office fined Reddit £14.47 million, finding it had processed children's data without effective age assurance and without a data-protection impact assessment for years.

In October 2024 Reddit changed its rules so moderators could no longer switch a community to private or NSFW without first getting administrator approval — a move the company tied to user expectations but which critics saw as a direct curb on the protest tactic that powered the 2023 blackouts.

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.

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.

During the GamerGate harassment campaign, Reddit communities — most prominently r/KotakuInAction — served as a major hub for coordination and amplification, as targets including Zoe Quinn, Brianna Wu, and Anita Sarkeesian faced doxxing, threats, and forced evacuations from their homes.

Indonesia blocked Reddit (alongside Vimeo and Imgur) in 2014 under its 'Internet Positif' anti-pornography filtering regime, and the block has persisted for over a decade.

In October 2014 Reddit acquired Alien Blue—the most popular unofficial iOS Reddit app, built by a single developer—and made it the company's first official mobile app, an admission that outsiders had built mobile Reddit before Reddit did.

Reddit confirmed it had globally banned several moderators of large adult communities, including r/nsfw, after they accepted bribes from a spammer to approve content — one of the company's clearest admissions of mod pay-for-play.

In December 2014, after the Guardians of Peace breach of Sony Pictures, Redditors used r/SonyGOP to index and link the leaked emails, scripts, salaries, and employee data — until Reddit removed the subreddit and banned its lone moderator following DMCA pressure from Sony.

Moderators of r/technology, then a Reddit default subreddit, were exposed in April 2014 for secretly using AutoModerator to delete any submission whose title contained ~50 banned keywords including 'NSA', 'Snowden', 'Bitcoin', and 'net neutrality'. Reddit removed the subreddit from its default list in response.

Ben Eisenkop, the wildly popular ecology educator known on Reddit as Unidan, was banned in July 2014 after admins found he used at least five sockpuppet accounts to upvote his own content and downvote a user he was arguing with over whether jackdaws are crows.

In June 2013 Reddit banned the entire Quickmeme domain site-wide after r/AdviceAnimals moderators presented evidence that the meme site's owner had used bot accounts to upvote Quickmeme links and bury competitors.

On 17 July 2013, Reddit removed two of its most prominent and most criticized communities — r/atheism and r/politics — from its default subreddit list, a curation decision that underscored the company's editorial power over what users see.

In April 2013, users of r/MensRights set out to identify the anonymous author of a feminist blog, but misidentified an uninvolved woman — who then received death threats at her school and workplace, prompting Reddit to threaten to shut the subreddit down.

The r/SilkRoad subreddit served as a public discussion hub for users of the Silk Road dark-net drug marketplace; when the FBI seized Silk Road and arrested Ross Ulbricht in October 2013, moderators briefly took the community private over identity-exposure concerns before reopening it.

In 2013 the founder and top moderator of r/atheism, 'skeen', was removed by other moderators citing his inactivity, opening the way for sweeping rule changes that split one of Reddit's largest communities.

In December 2013, users coordinating on r/MensRights flooded Occidental College's anonymous sexual-assault reporting form with roughly 400 false reports in about 36 hours, a clear case of subreddit-organized brigading against an external target.

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.

In 2012 Reddit banned the account SolInvictus — operated by Ian Miles Cheong — after the Daily Dot reported he used his moderator positions on some of Reddit's largest subreddits to push links from sites that paid him, including GlobalPost, which confirmed it had hired him as a paid 'social media consultant.'

On 18 January 2012, Reddit went dark for twelve hours to protest the Stop Online Piracy Act and the PROTECT IP Act, helping catalyze the largest coordinated online protest in history and contributing to both bills being shelved.

After Gawker journalist Adrian Chen unmasked the moderator 'Violentacrez,' volunteer moderators of several large subreddits — including r/politics — retaliated by banning all links to Gawker Media sites, exposing the tension between Reddit's anti-doxxing norms and press accountability.

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.

CEO Yishan Wong formalized a sweeping 'we stand for free speech' policy in the wake of the Gawker outing of moderator 'Violentacrez,' setting a content-permissiveness stance that defined and dogged Reddit for years.

In October 2011 Reddit closed r/reddit.com, the site's original catch-all community, and expanded its curated default subreddits to twenty—an under-recognized governance shift that put admins in charge of what the front page, and Reddit's culture, would become.

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.

In early 2010 Reddit erupted over 'Saydrah', a prominent moderator revealed to work for a content company while moderating communities her employer's material could appear in — an early reckoning over undisclosed conflicts of interest and power-user influence.

For over a decade Reddit had no usable mobile app of its own, so a cottage industry of independent developers—Alien Blue, Apollo, Reddit is Fun, Sync, BaconReader—built the mobile Reddit millions used, until Reddit's 2023 API pricing wiped the ecosystem out.

Reddit launched in June 2005 out of Y Combinator's first class and grew into 'the front page of the internet' on a near-absolutist free-speech ethos that would later collide with hate, harassment and child-safety scandals.
