VAC, Overwatch and trust factor: how a Counter-Strike ban actually happens

VAC, Game Bans and CS2 Competitive Cooldowns

Valve draws a sharp distinction between its three main anti-cheat and competitive integrity systems in CS2: Valve Anti-Cheat (VAC) bans, developer-issued game bans, and competitive cooldowns. Each serves a different purpose and has different effects, but they are separate systems and should not be conflated.

What is a VAC Ban?

VAC has become a key tool for weeding out cheaters. A VAC ban is a permanent ban from official, VAC-protected servers in Counter Strike: 2 (CS2) or any VAC-protected game. VAC bans are automated and have no manual appeal process, according to Valve. The system is triggered when a VAC client detects cheating software installed on the player's machine.

If VAC detects cheating on your account, you will be banned for life from playing your VAC-protected games, sharing servers, or making trades. VAC bans can't be lifted by Steam Support, Valve says, but they are automatically reversed if the system determines the ban was issued in error.

While it sounds draconian, a VAC ban only takes effect when a computer with identifiable cheats installed connects to a VAC-secured server.

A VAC ban applies to the specific game in which the cheat was detected, banning the account from that game on VAC-secured servers.

VAC bans can also apply where an account uses a phone number tied to other accounts that connect to a VAC-secured server while running cheat software. Since a VAC ban only applies to VAC-secured servers, banned accounts can still play single-player games, local LAN games, and multiplayer on non VAC-secured servers.

Counter-Cheats and Game Bans

Valve treats game bans differently. A game ban is an action taken and implemented by a game's own developers, in response to a player negatively affecting the game systems, other players. Like VAC, game bans can prevent players from participating in online games and trading in-game items. Unlike VAC, game bans don't affect your ability to use Steam as a media hub, but they do appear on your account profile.

Valve says the game developer is solely responsible for the decision to apply a game ban, and its duration.

You have little recourse if you're game-banned in CS2. That's because unlike VAC, game bans reflect the game developer's own decision. A game ban cannot prevent you from launching the game offline, nor from using Steam itself.

Only permanent game bans appear on a user's profile; temporary game bans or suspensions are not displayed.

Valve's Steam Subscriber Agreement spells out its ability to restrict account functions for illegal behavior, cheating or general troublemaking. The agreement says Valve may restrict or terminate an account or a particular subscription for conduct that is illegal, constitutes a cheat, or otherwise negatively affects other subscribers' enjoyment of Steam.

A third type, competitive cooldowns, applies only to CS2's competitive modes. Valve says these cooldowns are temporary, and CS2 game bans are issued when a player attempts to circumvent or interfere with game systems to the detriment of others.

Overwatch and trust factor are a different matter. Valve has never published how either one works, and that opacity is deliberate: a system that told you exactly what it measured would tell a cheater exactly what to avoid. What can be said is what Valve states plainly — that trust factor is derived from your behaviour across Steam rather than from any single match, and that it shapes who you are matched with rather than issuing bans.

The practical limit is clear: Valve can restrict accounts under its Subscriber Agreement, VAC bans are permanent and not manually appealable, and developer game bans follow the developer's own decision.
