- Valve Anti-Cheat (VAC) bans are permanent and non-negotiable.
- You cannot appeal or request any form of investigation on your applied ban(s).

1 VAC ban on record | Info
193 day(s) since last ban

引用自 Steam Support：

Can you tell me what program or software caused my VAC ban?
No. We do not disclose the cheats that were detected while connected to a VAC-secured server that resulted in a VAC ban. We have detailed records for each VAC ban, however, releasing this information would only benefit cheat developers. The VAC team regularly investigates claims of false VAC bans to increase the effectiveness of Valve Anti-Cheat.

引用自 Steam Support：

Can I appeal my VAC ban?
No. VAC bans cannot be appealed. If a VAC ban is issued incorrectly it will be automatically removed after investigation, but Steam Support does not manually remove VAC bans applied to accounts for any reason.
