My issue has been resolved, but it decided under pressure from the public forum.
April 14 the buyer of the account was contacted to me and explained the situation.
The account he bought from well-known rogue Pelk for 0,03 BTC, of course, not making sure the rights of the latter on account.
April 15, the buyer gave me back access to my account, but unfortunately, he managed to destroy all my personal correspondence (at least in the restoration of this property administration may help?).
Thanks to everyone who took part in the defense of my rights and ask those who have left negative trust on my account, delete it.
Signature and avatar restored. The posts that I not wrote removed.
But unfortunately, personal messages was removed, they contained very valuable information for me...
P/S: Not forget for sign message now
