Account disabled on June 7 — "This organization has been disabled" — requesting manual review (Max 5x, China user)

My Claude account was disabled on June 7th with no prior warning. The error message I get is:

This organization has been disabled.

My situation
I'm a developer based in China. I've been a paying Max 5x subscriber and use Claude Code through the official CLI for my daily work — chatting, coding, debugging, project architecture, and some research/writing.

I suspect the disable was triggered by my VPN. Claude isn't directly accessible in China, so I connect through a VPN, which probably makes my IP pattern look abnormal to the automated system.
What I want to clarify

• Only official Claude Code CLI. I have never used Cline, OpenCode, Cursor, or any other third-party client to access Claude.
• Normal usage. Development work, code review, some writing and research. Nothing automated, no scraping, no abuse.
• No prior warnings. I never received any safeguard warning before the account was disabled.
• Data I can't afford to lose. My account has ongoing projects and conversations built up over time.

What I've tried

• The appeal form on the help center redirects me back to the Claude chat interface (which I can't access), so I can't submit it.
• I've sent emails to support@anthropic.com and usersafety@anthropic.com.

I'm posting here because those other channels haven't gotten a response yet and I'm hoping someone on the team can take a look. I completely understand the need for automated safeguards — I just want a human to review my account and see that I'm a real, legitimate user.
