alt Hacker NewsReminds me of repl.it, which perma-blocked my newly created account before I even had a chance to type in e-mail verification code; in fact the notice about account block came before the one-time e-mail verification code.
I still wonder what did I do wrong (support isn't responsive). But it's true that we're both safe from having a user/vendor relationship now.
This happens to me when I inherit phone numbers previously flagged for fraud, then try to sign up for new services. My email is clean (I'm not a fraudster) but they ban me on sight based on association with a bad number since I never bother with the transfer process.
I always have to deal with this for the first year after changing carriers.
