Your VAC is permanent, if you want to play CS2 - create new account.
Also it doesn't sound like he's your friend.

You should have read the info linked on your profile. Valve answer that very question.

No. Any bans added to an account will remain regardless of who was using the account at the time the infraction occurred. Ultimately, the use and security of your Steam account are your responsibility.

That means your story is bull. Not that it matters really, as all VAC bans are indeed permanent.

引用自 Pinky：

can i do something about that?

Yep. You can make a new account and use that one to play on secure servers, or play from this account if any nonsecure servers are available for the game that the ban is for. That's all you can do.

can i do something about that?

Yes, you can do something about that. You can make a new account and stop letting your "friend" use it.

thanks a lot!

So the account was used to cheat and the account was banned, not you, have the loyal friend compensate you.

1 VAC ban on record | Info
1533 day(s) since last ban

irrelevant who used the account. vacbans are permanent

They don't care who used the account .... and as said account security is YOUR responsibility and ONLY your responsibility .... you agreed to that when you created the account

Cool story Bruh, too bad steam support will not remove bans from purchased accounts
