Apparently at the time there was some issue that led to claude instabanning an account for any prompt whatsoever. Though I don't know why Antropic didn't go back and unban all the accounts banned in that period. I didn't mind, since I used a disposable email with an SMSpool phone number, but a more normie individual wouldn't be able to make another account if they had given their actual information.
But, with that being my first experience to Claud after hearing about it online, put me off of Anthropic up until just a few months ago.
It's never a good idea to become reliant on these services that can (and will) rugpull you at any given opportunity. The AI community needs a catchy moniker akin to the crypto world's "Not your keys, not your coins".
