But a list isnt a so good idea, because only a few players visit the forum. I think their names should have a signal, like a red * in the end. So, if we see a cheater joining our games, we can drop it, isolating these bad guys and preventing them of taking points from the honorable players.
Hmm, a red *? Maybe a little word, like "CHEATER" after his names. Or "!!!CHEATER!!!"... Well, the important is they are easily identified.
