VAC is a Steam anti-cheat (detects illegal software) system which automatically detects unauthorised software.
We do not do any VAC bans on accounts here. Only Steam will give out VAC bans.
If a player is banned by VAC, he/she will receive the following penalties.
1) Cannot purchase any VAC applied Steam games with this account.
2) Cannot play VAC applied games.
3) Cannot appeal. If banned by mistake, the account will be unbanned after a certain period of time.
4) Cannot receive VAC applied game as gifts.
5) Cannot merge items to another account.
