my account just got hacked, too. The person changed the password and mail-adress. All I could do is to lock the account. I have no idea how they could find out my password, since I did not save it anywhere and have firewall and antimalware software installed... how can I get back in charge of my old account? (Atompeace).
Same thing here, it happened to me yesterday. All I could do is to lock the account, but not sure if it really has been locked.
I didn't put a Bitcoin address to that account. It seems if no Bitcoin address, no way to recover. But I am thinking, by common sense, bitcointalk.org should have all the original registeration info in its server which user cannot reach and change. Theoretically, the admin should identify the owner of the account by the registered email (that one from the very beginning), so at least can be reset to the registered email.
