It's a game ban.

Why are game bans issued?
Game bans in Counter-Strike 2 are issued when a player attempts to circumvent or interfere with game systems to the detriment of others.

Examples include:
Cheating.
Manipulation of matchmaking rank by deranking or falsely increasing your Skill Group or Counter-Strike Rating.
Botting and/or automation.
Intentionally interfering with the normal operation of game servers or other players.
Game Bans for all of the above are not removed by Steam Support.

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

У тебя ИГРОВОЙ бан, а не VAC. Он постоянный для CS2. Это пожизненный бан. Ты знаешь, что сделал. Полагаю, ты читерил. Теперь все твои вещи, вероятно, заблокированы на твоём аккаунте. Наслаждайся, сынок.
