A user reported their Claude account was suspended immediately after purchasing a subscription. The payment processed successfully, but the user received a ban notification within minutes. This appears to be part of a pattern where certain payment methods trigger automated account suspension, raising questions about Anthropic's payment verification system and customer experience for developers relying on their AI tools.

Users speculate several potential causes, including 3D Secure authentication processes, business credit card rejection, or VPN usage triggering false positives. One commenter noted they were charged even after being banned, while another suggested the service might have difficulty handling business credit cards due to higher processing fees in certain regions like the EU. Location-based restrictions may also play a role.

The incident highlights technical challenges in AI service payment processing and account verification systems. Some users mentioned Anthropic's own AI might be responsible for these false positives through "hallucinations." The issue impacts user trust and suggests Anthropic needs to refine their automated fraud detection to balance security with customer experience when dealing with different payment methods and user locations.
