I once got a new phone number and I tried to register to Twitter; apparently it's already used, by an account that is banned. I managed to login to the account but there is no way to ask what's up. I followed the procedures, even wrote them an e-mail that as a EU citizen, I'd want them to forget anything related to me and my phone number. No reply. Still probably doesn't work, don't care all that much though. Wasn't a Twitter user before, wasn't one after.
