Since I wasn't using my account for a while, I just thought it was a little bit strange when I was trying to access the account and it was telling me that the password was wrong. So I tried to go through the recovery but it was telling me the email was wrong... that's when I saw something was terribly wrong... I'm still trying to reason how the bastard was able to do that...
Probably he got your password through the database leak in the year 2015 happened here, back then I was not a member but during that time a leaked database of tons of accounts of bitcointalk was being sold on darknet markets which you can find with TOR browser. Once he got your password, he changed your email and password and is using your account since then I believe.
As I said the only way for you to recover your account is by signing a message from an old wallet you have staked (if you have staked) in the thread I told you above. There is no other way as far as I know.
Yeah, I still have access to my old wallets. it is a blockchain wallet. what do you mean by "if my wallet was staked"?
