Glad that has not happened to me. I have had a few obnoxious players and obsessive ones that wanted to game EVERY day of the week, though none I have had to get the police involved to deal with.
I say this as I had a guy I kicked out of a 3.5 game, he started mailing me dead animals, verbal sexual threats to my wife, etc till I got police involved. On the 1 year anniversary of him joining my game, he mailed me a "Birthday" card . "Happy Birthday." I would laugh if it didn't happen to me. Many people do not believe something like this can happen, that this only happens to women. Google it.
