A developer shares their experience of being unexpectedly banned from GitHub with no explanation, no email notification, and a frustrating support process that required having an active account to appeal. The ban erased all their contributions, comments, and pull requests, and blocked access to features like code search, GitHub Sponsors, CI artifacts, and HACS for Home Assistant. The author speculates the ban may have been triggered by adblocker filter lists, an ad-blocking tool for a VR game, or a joke repo using Unicode text-reversal characters. They urge developers to migrate away from GitHub given the risk of sudden account erasure. The account was reinstated roughly three hours after the post was published, seemingly prompted by the public attention.
