why can not I play Call of Duty: Ghosts on the network?

Good afternoon. I had a very large problema.19.05.2014 I played her favorite game. during the game got black screen and then kicked in the lobby and an inscription that my profile banned: http://steamcommunity.com/sharedfiles/filedetails/?id=287984252 Now when you go to a multiplayer game that I wrote forever banned: http://steamcommunity.com/sharedfiles/filedetails/?id=287986524 I can not understand how this happened. I've never used any third-party programs and cheats for the game. vac ban permanent, not temporary ... for what? I myself hate cheaters and people playing is not fair, always write REPORTS them. How is this possible? this blot on my reputation honest player in the community of gamers. while in my profile steam vac ban is not displayed. possible to inspect my data on this? find out what's wrong? fix this error? I very much hope that you will help me ... agree to any inspection ... my accounthttp://steamcommunity.com/profiles/76561198039057641/ grateful for the answer in advance
