Warning: Anthropic's "Gift Max" exploit drained €800+, ruined my credit, and got me banned.

Heads up to anyone here using Claude/Anthropic as an alternative. If you have a card saved on their platform, remove it now. I’m a data science student in Germany. On April 27th, my account was hit with over €800 in unauthorized "Gift Max" charges. The Exploit: 2FA was active. 3-D Secure was bypassed (I received the bank emails, but they were never opened or authorized). The gift codes were generated and instantly redeemed by a third party. Anthropic’s own status page admitted to "Elevated billing errors and unauthorized subscription changes" that same day.
