Game ban, nothing to do with VAC or this forum.

Took you 830 days to notice the ban, in any case, if it's for a VALVe game, it's permanent, no appeals.

You have no business to be in your dads account, you should create your own account.

Be glad it's only a game ban and not a account termination for account sharing.

It's a game ban, cheats aren't necessary, and you should know that; you've had over 800 days to find out.

Your father isn't allowed to give you access to his account, and since it's not your account, it's not your problem.

Hello, STEAM, I would like to say that I did not use third-party files to gain advantage in my favor, that is, cheats, my dad's account and I wanted to get back the regular account without Vac.

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

let us guess, either you bought the account or you suddenly want to sell/trade items what is attached to the account. Bans are permanent

Cool story bro, too bad that stories are not going to change anything.. Make a new account and move on.
