Someone post the release of new crypto currency from my account
https://bitcointalk.org/index.php?topic=2226897.0

In this message they assure that this is their account
https://bitcointalk.org/index.php?topic=2226897.msg22528785#msg22528785

Please tell me why I can not recover the stolen account? because I have a signed message from the address that is specified for a long time in the profile of the BitcoiBus account.

Please help me to reecover my BitcoinBus account !
