Hello, players and users of a forum.
Faced such problem, during my absence in Steam my account was hacked and violated from it rules of the game in the investigation of what on my account it was blocked.
Tell whether it is possible to solve this problem somehow? Where it is possible to address what to me could remove this blocking? 
I am the ordinary player never breaking rules of the game and playing always fair, I hope for amnesty.
