No your Game ban is permanent regardless if your account was hijacked at the time. Your account security is your responsibility.

Steam accounts have never been "hacked", only hijacked through social engineering. Why spend the time and trouble to "hack" an account when there are many people that willingly give out their account information for greed. We see it every single day and there is always another user that thinks they know it all but actually have zero clue and end up giving out all their account credentials to the hijacker.

The account has a GAME ban

Game bans have nothing to do with VAC or this forum

Users are responsible for the security of the account and all that happens on it

So my account got hacked and cheated ingame and got me Vac banned i have all the evidence that i did get hacked, is there a way i can get unbanned as i have not got skins in my account that cant be used cause of a hacker getting into my steam account

1 game ban on record | Info
7 day(s) since last ban

20+ year old account and don't understand that it is irrelevant who used the account and that the ban is permanent.

OP like i said, it is irrelevant who used your account, Bans are delayed on purpose and bans are permanent
