I'm by no means a security freak but I do like to think I keep my accounts locked down. The email associated with the account was not hacked/stolen, and neither were any other accounts of any type of mine.
So I guess that someone, somehow guessed my password consisting of something personal... then changed my username to "swap546456".
Would I be able to get my other username back?
Also, since you said the IP history matches with the other account, would I possibly be able to get that IP history list to potentially see if the location (hoping whoever did it wasn't using a VPN) lines up with anyone I know for potential "security troubleshooting"? (I don't know how to word it). Thank You.
