Sorry to hear you got hacked that's really shitty. But I don't think that it'll be possible for you to reclaim that account. Now don't take this the wrong way, I'm not accusing you of anything, I'm just considering possible scenarios. Who's to say you didn't sell the account yourself and now that you have the Bitcoins, you're just trying to get the account back and keep the BTC? You see what I'm getting at? If that were to be the case then it wouldn't be fair on the buyer to have paid for the account and then having to return it without getting his money back. You'll need better proof before the mods will consider taking action.
I sincerely hope you get your account back if you're truly the victim here. Good luck.
