Anthropic bans 11.4M Claude accounts in H1 2026

On July 23, Anthropic updated a safety and trust report in its transparency hub, adding a dedicated "Banned Accounts" section. According to an IT之家 report published on October 11, that report states that Claude banned a total of 11.4 million accounts in the first half of 2026. Over the same period, 398,000 appeals were submitted, and only 42,000 of them succeeded — roughly nine out of every ten appeals were rejected. The report also notes that Anthropic updated its Claude usage policy around the same time, explicitly prohibiting insults or cruel treatment of Claude. The IT之家 account adds that the July report resurfaced during a holiday period and spread widely online, with discussion around "Claude account bans" reaching the million level. The material does not explain why the accounts were banned, what follow-up steps Anthropic took, or any further official statement, so the account stops at the report and the policy update themselves.
