I'd guess that DDoS attacker hacked mah account as well or the beta is leaking passwords. I'm not getting the reason how am I hacked? However, I've sent you a pm(theymos) for mah account recovery. How about checking 'em(mah pm)?
My guess is both of your above guesses are full of crap since your saying he also "hacked" your btc wallet.
So, you likely have malicious software on your computer and I'm guessing is still there now.
Also, this thread is to notify users of this DDoS extortion attempt and/or possible future downtime.
You posting in this thread to ask Theymos to check his PMs about your account reset is offtopic.
