*"Reporting of Suspected Cheating
Suspected cheats are NOT to be named publicly on the boards by forum members. Any post which names suspected cheats will be edited or deleted without notice. Individual leagues may have their own reporting procedure for such actions."*
If need be, PM one of the Cyanide/Focus reps.
Also note that they don't seem to care about this game anymore, given the lack of responses to posts here and in the Tech forum.
