VAC is enabled on all multiplayer servers, public and private. Any modifications to the game other than editing config files can result in a VAC ban. Examples of such modifications include but are not limited to console enablers, VAC disablers, and server hosting mods.
VAC Bans versus Server Bans
The best indicator that your account has been banned by VAC is if you receive this message when attempting to access a VAC-secure server:
"Your connection to this secure server has been rejected. Because of past cheating violations, you have been banned from playing on all secure servers"
If you receive an error message stating "STEAMID IS BANNED" (or other similar messages) when attempting to connect to a server, your account is not banned by VAC - server administrators may ban you from a particular server (we cannot prevent this - whoever runs the server can ban players for any reason they desire).
If you find that you are banned from a large number of servers but your VAC status is in good standing, you have likely been banned by a third-party ban tool, such as Steambans or Punkbuster. These third-party tools are used by a large number of servers sharing a common database of banned IDs. These tools are unrelated to Steam and we cannot assist you in resolving this issue.
You will not be banned by the VAC system unless you login to a VAC-secure server with a cheat installed on your computer.
