Holy crap, Claude has started checking IDs one by one! Some people say their accounts were blocked right after passport verification! These past two days, many people have been prompted with identity verification, requiring original physical identification documents, and possibly even a selfie on their phone. Some people reported being blocked right after passport verification, following the notification and account suspension. Others have been able to continue using their accounts normally after verification, so don't panic. My first reaction upon seeing this news was to check ~/.claude. CLAUDE.md, my custom skills, and various settings are all in this one folder. Conversation logs are stored in plaintext in ~/.claude/projects, automatically cleared by default after 30 days. You can appeal if your account is gone, but if you lose this folder, it's truly gone. I'm backing up the entire folder today. I also checked the logs to see if any exchange API keys were pasted. If so, I'll immediately invalidate and recreate them at the exchange. An account suspension might just stop you from working, but losing a key means real financial loss. If you've already been blocked, don't rush to create a new account. Using a new account to bypass the ban is itself listed as a violation of the usage policy. Log in to http://claude.ai with your original account; appeals, data export, and account deletion are all on the same screen. The export link expires in 24 hours; download immediately upon receiving the email. Don't expect to get your subscription fee back; there are no refunds for termination due to violations. There are also people selling "American KYC bypass + US SIM card subscription": Pro 329 yuan, Max 2999 yuan. The purchased identity will still be banned, and your money might be stolen. This is blatant exploitation. To avoid being banned, don't try to find tricks. You must genuinely be in the supported region; your ID, payment card, and account must all belong to you; do not share or lend them. The account belongs to Anthropic, ~/.claude is yours; hold onto your share first.
