There were some senseless and idiotic comments (in Russian) made from your account - so it was obvious your account is not controlled by you any more :-(

As already told, you need to complain about this matter to Mike Mirzayanov. It seems that he (or other administration team members) already undertook some measures and they possibly will find a way to identify you and return your account to you. I suppose it would be easier to prove your rights if you still have access to e-mail address which you used to register account (i.e. if your e-mail was not hacked also).

Anyway it is not great idea to discuss this in the blogs (and to create secondary account maybe). There are several reasons for which you should hold a communication directly and privately with administration of the resource. Good luck!
