Tech Connect Magazine links to the SBS, a shared ban system for Steam based games.  If you are losing your cool to cheaters, give the system a shot, hopefully it will make blasting away opponents even more fun.
“it’s time to get rid of cheaters, to ban them from our game rooms, to drive them to the very edge of the internet, and push them right over, with Sharedbans’ SBS plugin.

With its SteamID-based validation system, SBS is a server-based plugin for all Steam-based games which offers a permanent ban list approved by professionals, compatibility with all existing plugins and server-side mods, and dedicated support staff.”
