Anthropic has implemented a strict KYC check for Claude users showing suspicious activity such as frequent IP changes or VPN usage. When the system flags an account, it demands an identity document for further verification.

Uploading a Russian foreign passport triggers an immediate account ban, with no appeal option and no refund of subscription fees. The crackdown also hits Chinese citizens, while long‑term visas or residence permits from other countries are ignored by the automated check.

Reddit threads and forums are ablaze with criticism; affected users are urged to request chargebacks from their banks because Anthropic’s support remains silent and refuses to return unused subscription money. The episode fuels growing discontent over the company’s verification policy.
