Anthropic Bans Insulting Claude — Rule Violators Could Face Account Suspension

Anthropic has updated the rules for using its artificial intelligence services. The new rules, which will take effect on November 12, 2026, include one notable provision: users are prohibited from systematically engaging in abusive and cruel behavior toward Claude AI models without cause.

Under the new rules, if a user is persistently abusive during a conversation with Claude, the chatbot may end the conversation itself and decline to respond to that user's messages for a certain period. In more serious cases, Anthropic may take additional action, including suspending the account.

However, the company emphasizes that account suspension will be applied only in exceptional cases. This refers to users who regularly behave cruelly toward the AI without a clear purpose. Expressing dissatisfaction with responses, criticizing Claude, creating dark-themed creative writing, and testing the model's capabilities are not covered by the ban.

Anthropic's primary response will be to end the problematic conversation rather than immediately punish the user. In other words, disliking the model's response or engaging in a heated discussion with it does not in itself constitute a violation of the rules.

The updated policy does not stop there. Using Anthropic's services to create fake accounts and fictitious identities for the purpose of deceiving people is also prohibited. The new rules will apply to Claude.ai, Claude Code, the API, and Anthropic's other services and will take effect on November 12, 2026.
