Claude's updated usage rules take effect November 12
Anthropic published a revised Usage Policy for Claude on October 8, effective November 12. Most changes clarify existing rules, and rules against fake accounts and hidden-sponsor messaging now sit in one new deceptive campaigns section.
If Claude shapes decisions about someone's health, finances, legal rights or livelihood, Anthropic already requires a qualified person who can change its recommendations, and the affected person must be told AI was used. The rewritten section now lists which uses count. A new rule targets sustained cruelty toward the model, and Anthropic says it excludes ordinary frustration and dark creative themes.
Your moveBefore November 12, check your client work against the High-risk Use Case Requirements section. If you run social or marketing campaigns, also read the deceptive campaigns section.
