Summary

A safety system bug incorrectly banned approximately 8,400 accounts over several months by applying bans instead of temporary upload pauses during content review. All affected accounts have been reinstated, and the platform is implementing additional safeguards to prevent similar issues and reduce false positives in safety systems.

    This weekend, our safety systems incorrectly triggered and banned around 200 accounts. Everyone affected has been reinstated. Here's what happened. A thread 🧵

    There’s currently a vulnerability in Discord’s AI moderation that detects any and all square grid images, such as spreadsheets, chessboards, Minecraft inventories, white & gray transparent backgrounds… as CSAM and will permanently ban your account. To keep your account safe, I would recommend NOT sending any sort of images anywhere until this vulnerability is fixed. If you are a server owner or admin, I would highly recommend to disable all image and gif/embed perms in your server for the time being. To @discord @discord_support, this vulnerability needs to be fixed immediately with all false bans overturned. Additionally, AI moderation needs to be scrapped and replaced with humans. This is exactly why companies shouldn’t be using clankers to decide whether accounts should be banned or not. Losing a Discord account to something as unfair as this can be extremely devastating and affect users severely, and every day millions of users are affected by false AI bans. This needs to be stopped. If you would like to spread awareness about this, feel free to like & repost.

    Our systems flag content by matching it against known harmful material. This kind of similarity matching can produce false positives, which is why a member of our Trust & Safety team always reviews flagged content before any action is taken. The intended behavior is to temporarily pause uploads during that review, not ban the account.

    We had a bug that caused the latter. When our staff reviewed and cleared those accounts, the same bug prevented the ban from being lifted automatically, so it just stayed in place. Around 8,200 accounts were affected from May 2026 through last week, plus the 200 more this past weekend. We've unbanned everyone affected by this bug.

    We know that's not a satisfying explanation if this was your account, and we should have caught this sooner. We're working on better safeguards so this can't quietly happen again, and more broadly, on making sure our safety systems don't penalize people who did nothing wrong.
