VAC detected a known cheat and a permanent ban was issued.

Bans can also be given for skin changers, phone number sharing, library sharing, account sharing or changing core files of the game.

Bans that have been issued incorrectly, are usually being removed automatically within few days to weeks.

Your ban is OLD and permanent.

"VAC banned for a correct reason"

The ban is 659 days old.

It was applied correctly.

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 automatically be removed.

"Can I appeal my VAC ban?"

No. VAC bans cannot be appealed. If a VAC ban is issued incorrectly it will be automatically removed after investigation, but Steam Support does not manually remove VAC bans applied to accounts for any reason.

I didn't play from year 2018, downloaded it today, and saw that I have ban.
I didn't use any cheats, and I didn't give my acoount to anyone, so please, take it off, I just want to play your game

the way you worded your post here is like implying this

1) i just recently bought this steam account from a 3rd party website without realizing that it already gotten VAC ban for 669 days from a certain game.

there isn't a need to re-download and reinstall the game when it is all along installed on the steam account totally.

the concrete evidence of what i state is here

Steam was first released on Windows: 12. September 2003. 1970 PCs weren't a thing, Valve nonexistent and Steam not even a dream.

The same thing can happen if you use the Help > system information selection in the top of Steam. It displays a very old date for some reason.
