It has been revealed that over 8,000 users were mistakenly banned from Discord for posting screenshots or other harmless images containing grid patterns.

Discord has announced that a bug caused it to mistakenly ban over 8,000 accounts since May 2026, including users who posted images. Users who posted images such as Minecraft inventory screens or grid-like images resembling chessboards were among those affected, and Discord says that the affected accounts have already been restored.

This weekend, our safety systems incorrectly triggered and banned around 200 accounts. Everyone affected has been reinstated.

Here's what happened. A thread ???? https://t.co/wXH32iiv8I

Discord operates a security system that matches posted images against known harmful content to prevent the posting of harmful images. This system is designed to detect and stop the spread of illegal and harmful images, such as child sexual abuse content.

The problem stems from 'false positives' occurring in this matching system, where harmless images were mistakenly identified as harmful content. Images such as chessboards and game screens containing grid patterns, as well as other harmless images, were mistakenly detected. Images that were falsely detected also included brick walls, pool tiles, keyboards, puzzle game screens, and graph paper.

The system was supposed to temporarily restrict image posting by the account in question if it detected a suspicious image, and then have a staff member review the content. However, due to a malfunction, the process that should have been to temporarily restrict uploads was instead executed as a complete ban on the account.

Discord co-founder and chief technology officer Stanislav Vishnevsky stated that the bug affected approximately 200 users who posted grid-patterned images after May 2026, as well as approximately 8,000 other users who posted harmless images.

I want to apologize for a bug we fixed that over the weekend wrongly banned ~200 users over grid-like images, and ~8,000 more since May over other benign images. Everyone affected has now been unbanned. Learn more about how happened from this @discord_support thread. https://t.co/W8koqIXiKH

Furthermore, even accounts whose content was reviewed by staff and deemed acceptable were not automatically unbanned due to another glitch. As a result, accounts that should have been restored after the review process remained suspended, prolonging the impact. Discord has stated that all accounts suspended due to the glitch have now been restored.

Discord has not disclosed the specific reason why the grid-patterned image was determined to match known harmful content. The company explains that the core issue was a false positive in its safety system, which matches uploaded images with known harmful content, resulting in a full account ban instead of the intended temporary upload restriction.
