Moderation & Power Abuse

A 2021 Reddit bug that printed internal removal reasons — published in a 2026 teardown — revealed the machinery behind Reddit's silent removals: an internal system called 'spamurai,' Google's Perspective API scoring private messages, TLS and browser fingerprinting, and ISP-level profiling of users.

A 2024 study offered the most rigorous measurement yet of Reddit's June 2020 'Great Ban': while most affected users left or became less toxic, roughly 5% reacted by sharply increasing their toxicity — quantifying both the efficacy and the radicalizing unintended consequences of mass deplatforming.

In June 2022 Reddit banned r/TumblrInAction, an 'anti-SJW' community of roughly half a million members, together with its smaller sister subreddit r/SocialJusticeInAction, citing its rule against promoting hate — a removal the communities' moderators attributed to gender-critical content and which reignited debate over consistency in Reddit's enforcement.
