VAC

Is vac enabled on the barracks. Or the main menu aka (not in a game). If it is not enabled there then can trainers for camos/stats get you banned if you task manager close the hack before joining a game?

Using camo hacks and stuff can be detected by the server. If you have a camo that you have never unlocked before it is kind of obvious and I believe they reset all of your stats if found or may just ban you.
