AI Moderation Tools Erase Years of Reddit History, Raising Concerns
In April, Reddit's AI moderation tools automatically removed dozens of comments and posts from the r/AskHistorians subreddit, some dating back 10 years. The deletions occurred without warning, and moderators, including Dr. Sarah Gilbert, were unable to restore the content. The removed posts all linked to Rare Historical Photos, a historical image-sharing website, leading moderators to suspect Reddit flagged the site as spam. This incident highlights the risks of relying on AI to moderate social media, as it can inadvertently erase valuable community archives. Reddit has not commented on the issue. The removals may have skewed metrics used to demonstrate AI moderation effectiveness.
