Stanislav Vishnevskiy, Discord cofounder and chief technology officer, writes that the bug impacted around 200 users who posted “grid-like” pictures, in addition to about 8,000 people who posted “other benign images” since May 2026. “Everyone affected has now been unbanned,” Vishnevskiy says.
In a thread on X, Discord writes that its safety system is designed to flag content by “matching it against known harmful material.” This system can produce “false positives,” Discord explains, which is when an employee would step in to review the flagged content. But instead of just temporarily preventing the account from uploading content during the review, a glitch led its system to ban users entirely.
“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 says.
