Misinformation & Conspiracy

A January 2026 Reddit post by a supposed food-delivery 'whistleblower' — complete with a fake 18-page document and AI-generated employee badge — drew tens of thousands of upvotes and tens of millions of views before being exposed as AI-fabricated.

Reddit's AI 'Answers' feature surfaced dangerous medical misinformation in health subreddits — including pointing pain-management questions toward an illegal narcotic and an unregulated herbal substance — and moderators reported they could not turn it off.

Because Reddit ads appear inside community conversations rather than a curated feed, advertisers have long worried about placement next to misinformation, hate, or explicit content — driving a 2024-2025 scramble for third-party brand-safety controls.

Former UFC champion Ronda Rousey's August 2024 AMA promoting a graphic novel was overrun by questions about a 2013 Sandy Hook conspiracy video she had reposted; days later she issued a lengthy apology.

After splitting from r/GME in 2021, r/Superstonk became the center of a self-reinforcing belief system organized around the 'Mother of All Short Squeezes' (MOASS) and a mass share-registration campaign, with skeptics dismissed as paid 'shills'.

Climate-misinformation researchers who traced ExxonMobil-linked disinformation across social media included Reddit's climate communities (r/climate, r/climatechange) in their analysis, situating the platform within a documented, industry-funded effort to muddy public understanding of climate science.

On 23 March 2022 Reddit quarantined r/GenZedong, a pro-CCP 'tankie' community of over 57,000 members, for hosting a high volume of disinformation about Russia's invasion of Ukraine.

On 1 March 2022 Reddit quarantined r/Russia, a community of over 265,000 members, for spreading disinformation about Russia's invasion of Ukraine, along with its sister subreddit r/RussiaPolitics.

u/N8theGr8 became a recurring example of Reddit's 'power moderator' problem — a single volunteer who, by 2021, moderated dozens of communities containing millions of members and organized a cross-subreddit protest demanding Reddit act on COVID-19 misinformation.

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 administrators permanently suspended the account of r/conspiracy's most prominent moderator, axolotl_peyotl, citing repeated content-policy violations — a direct admin removal of an entrenched head moderator that the community treated as both overdue and as admin overreach.

A baseless 2020 QAnon theory that the retailer Wayfair was trafficking children spread rapidly after appearing on r/conspiracy, leading to the harassment of real families whose missing-relative cases were dragged into the falsehood and straining a national anti-trafficking hotline.

On September 12, 2018 Reddit banned r/GreatAwakening — the largest QAnon hub — and roughly 18 related subreddits for inciting violence, harassment, and doxxing.

Reddit banned r/MillionDollarExtreme — the community tied to Sam Hyde's comedy troupe — on September 10, 2018 for violating its violent-content rules, two days before the QAnon sweep.

After the Parkland school shooting, conspiracy communities including r/conspiracy, r/The_Donald, and r/CBTS_Stream amplified false 'crisis actor' claims against teenage survivor David Hogg, who received death threats and was later swatted at his family's home.

Reddit hosted r/pizzagate, where the false 'Pizzagate' conspiracy was incubated and named individuals and a D.C. pizzeria were targeted; weeks after Reddit banned it for doxxing, a gunman fired a rifle inside the restaurant.

Fans of the comedy group Million Dollar Extreme repeatedly tricked media outlets and even a member of Congress into naming comedian Sam Hyde as the perpetrator of mass shootings — a recurring hoax circulated across Reddit and other platforms that injected false suspect names into breaking-news coverage.
