Discord has acknowledged that a bug in its AI moderation system accidentally banned more than 8,000 users over the past two months after harmless images — including spreadsheets, chess players, game textures, as well as white and gray transparent backgrounds — were mistakenly flagged as harmful content.
The company confirmed the problem had been affecting accounts since May, with another 200 users banned over the weekend before its team identified and fixed the problem. All affected accounts are currently in the process of being restored.
The incident highlights one of the growing challenges around AI-assisted moderation, as many platforms increasingly rely on automated systems to detect illegal or abusive material at scale.
In one detailed thread on XDiscord explained that its automated security system works by matching uploaded content against databases of known harmful material. While the technology is designed to catch illegal content, the company acknowledged that it can sometimes generate false positives. A human moderator reviews the content, but a bug caused the system to immediately ban the affected accounts.
“We’re working on better safeguards so this doesn’t happen again,” the company wrote.
Our systems flag content by matching it with known harmful material. This type of similarity matching can produce false positives, so a member of the Trust & Safety team always reviews flagged content before taking any action.
The intended behavior is to…

Throughout X and Redditusers claimed they were permanently banned simply for uploading images containing square grid patterns. Several users speculated that Discord’s AI moderation tools have become increasingly sensitive to grid-like patterns because they were previously used in attempts to cover up or mask NSFW and child exploitation content from automated detection systems.
Affected users have expressed their frustration on social media, with some arguing that permanent account bans based solely on automated detection can have serious consequences, particularly for users who rely on Discord for work, gaming communities, or long-distance social connections.
“Losing a Discord account to something as unfair as this can be extremely devastating and seriously affect users and every day millions of users are affected by fake AI bans. This needs to stop,” a user X he wrote.
My account was unfairly banned from your platform due to a bug in your AI automod detecting my GAME TEXTURES as CSAM. I need my account back as I am a gamemaster and use Discord for all my communication. I have requested a review of my suspension.@discord @discord_support pic.twitter.com/QfAkCIJo6S

Discord isn’t alone in having moderation issues due to automated systems. Last year, users of Instagram and Facebook Groups reported widespread unexplained account suspensions that many believed were caused by AI control systems. Although users have pointed to automation as the likely culprit, Meta has never publicly confirmed whether AI bugs are to blame. Now Meta’s Supervisory Board is pushing for increased transparency.
Tumblr last year also faced complaints from users who said their accounts were being suspended en masse without clear explanations.
