I don't even have an account with them but keep getting emails that my account is suspended due to suspicious activities (attempted login attempts, assumed dubious tweets/posts etc). I've reported numerous times over a year or so (eventually as so hard to contact them).I eventually get a response and is like being scolded for daring to report someone is using my email details "Your account was suspended due to multiple or repeat violations of the Twitter Rules. This account will not be restored.This case will now be closed and replies will not be monitored. "
