When the Bots Purge the Archive: Reddit’s AI Moderation Erased a Decade of r/AskHistorians Work

Reddit's AI moderation system has caused significant issues, including the deletion of a decade's worth of content from the r/AskHistorians subreddit, mistakenly flagging historical image links as spam. Similar problems have occurred on Discord, where AI incorrectly banned thousands of users for posting images of chessboards, and Meta platforms have faced complaints about AI-driven bans. These incidents highlight the risks of over-reliance on automated systems without sufficient human oversight, particularly concerning false positives that disproportionately affect marginalized communities and silence valuable contributions.
