Now that you have locked the account no one can use the account. The hacker probably used Tor or a VPN so he's unlikely to get caught. All you can do now is sign a message from an address posted on the account that has been hacked and send it to cyrus.
Otherwise you aren't going to get the account back.
his ip is: 195.11.169.69
i dont have the private key of the posted bitcoin addresses i have with my nick, they are just too old
my ip is static, they can verify my ip now is the same i used in most of my last posts, thats all i can provide, and some pictures of objects i posted long time ago.
i can prove my mail is mine too, if all they want accept is the private key of a very old address, i am done.
IP addresses aren't valid proof for the owner of the account as they can easily be manipulated and spoofed. The only way you are getting that account back is from signing an address. Have you sent an address via pm recently? as you can recover from them.
