I despise cheaters. The problem is that my group of players is small so I can not find replacements. I have killed PCs, taken players outside for a talks and even eaten two character sheets just to prove how much I hate cheating. I have added a D20 the size of a baseball so I can see the roles suspected cheaters are making, and still it occurs!
DM's, what are your stories of idiot players and how do you handle them?
