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

That's a game ban, not a vac ban, game bans have nothing to do with vac or this forum. Regardless, the ban is permanent and cannot be appealed against

As for why, click on the info link next to the ban notice on your profile, it's all explained in there

Also, these are community only forums, nobody from Valve is here or will read your post
