2/4D1 can detect cheat or it is only if player reporte you ?
3/If i got banned by VAC from MW2 i'am banned from mw3 too ?
4/ If i got banned from 4D1 i'am banned from VAC too ?
5/ If i playe with cheat on 4d1 VAC can detect it ?
6/ If i got banned from 4D1, i just need to create another account on the website and i can play again on 4d1 ?
