Counter-Strike 2 game bans are permanent, non-negotiable, and cannot be removed by Steam Support.

Can you tell me why I was game banned?
No. We do not disclose the reason for your game ban.

well if you wanted to know, you can go to your profile and click on the info button next to your gameban. Also bans don't happen because of one or two reports.
