So im banned on bo2 and i really want to play it again.
Can someone link me a bypass?
There used to be few methods but all of them are patched, you can't bypass VAC but you can prevent yourself from getting VACC'ed. Just use private paid hacks and such and never play too suspicious. Since you're banned forever I suggest you getting a new copy of Black Ops 2 on g2a.net (8-10$) or buy it somewhere else and create a new steam account and redeem it on that one.
