VAC bans are exclusively issued for cheating and are both permanent and non-negotiable.

I didn't get a VAC ban while playing the game. I got a VAC ban for no reason after 3 days of playing the game. I want to appeal this.

vac bans are delayed between detection and actual application to make it harder for cheaters to warn each other.

What can I do to get it checked again? I play on Faceit and I don't have any cheats. I didn't do it.

You should have read the FAQ in your profile.

Right from the start:
VAC bans are permanent, non-negotiable, and cannot be removed by Steam Support. If a VAC ban is determined to have been issued incorrectly, it will be removed automatically.

Also, Faceit uses VAC in addition to their own anti-cheat solution. The fact that you play on Faceit is not an excuse for the (in)accuracy of VAC.

How long does it take for a VAC ban to last if it is found to have been placed incorrectly?

Few days to weeks but i wouldn't hold my breath it being removed then.

Posting here doesn't remove any bans, those are checked regularly if given correctly and if not, they are automatically removed in time.

Posting here doesn't change anything.

There's no precise information on this; it could take hours, days, or even weeks.

However, the chance that a VAC ban is false and will therefore be removed is so small that we're talking about less than 0.1%.

I understand, I have no objection to that.

I understand, thank you for answering my questions.

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

bans are delayed on purpose. Vacban is for cheating, skinchangers is seen as cheats. If the ban is incorrect, then it will be removed within couple hours to about a month or so, after that, you have to accept the ban is permanent then

VAC BANS are for the detection if cheating software ONLY. The cheat program does not need to be running, VAC can find it..

The longest I've seen was just a little over a month. The majority of ban removals I've seen were 1 - 2 weeks, but that's when the bans were actually incorrectly issued according to Valve and not "incorrectly" issued according to the account owner.
