Discord mistakenly banned more than 8,000 accounts between May and July 2026 due to a bug in its safety system, the company confirmed following a wave of user complaints.
Affected users reported being banned for posting images containing grid patterns, including chessboards, game textures, and Minecraft inventories. Discord cofounder and CTO Stanislav Vishnevskiy said the bug impacted around 200 users who posted “grid-like” pictures, along with approximately 8,000 others who posted “other benign images” during the same period. Vishnevskiy confirmed that all affected accounts have since been unbanned.
According to Discord, its safety system works by matching uploaded content against known harmful material. When the system flags a potential match, a staff member is supposed to review it. During that review period, the intended behavior was to temporarily restrict the account from uploading content — not to issue a full ban. A bug, however, caused the system to ban users outright instead.
The problem compounded further during the review process. “When our staff reviewed and cleared those accounts, the same bug prevented the ban from being lifted automatically, so it just stayed in place,” Discord explained in a post on X.
The issue drew public attention over the past week as users began sharing reports of unexpected bans tied to seemingly harmless image posts. Discord’s statement and the subsequent unbanning of affected accounts followed that surge in user reports.
The incident highlights how automated content moderation systems can produce false positives, and suggests that bugs in the underlying infrastructure may prevent human review from correcting those errors in a timely way — leaving users locked out of their accounts without cause.
