In March 2026, an automated moderation system on Tumblr banned close to 200 accounts within a single afternoon, sending users generic notices citing an ‘internally-generated report’ with no explanation of the alleged violation. Some affected users said the bans disproportionately targeted accounts run by trans users, though Tumblr’s parent company Automattic said it found no evidence of that pattern. Automattic disabled the system, restored the banned accounts, and said it was working to fix the underlying issue.
