By analyzing the post history of that account you mentioned it is clearly shows that accounts had been changed hands from bitcoin discussion poster into altcoin signature spammer posting under less than one line.But you need to prove that your account then only you can recover your account.

Procedure to recover your account can be found here  : Recovering hacked accounts or accounts with lost passwords

But the recovery process will be much longer or forever so you can ask any of the DT member to tag that account until you recover it.
