Insult's from players in On-line
poker game's is something that does happen quite often, but only because they feel safe behind the confines of their own keyboard's, they are usually uneducated, wanna be bullies, who try to intimidate other's with their foul mouth, abusive behaviour, and yes! I agree should be punished, Usually they do get punished from far better players who take them out of a game, and they become the joke for everyone else left in the game.
Some do it on purpose, to try and put others on "Tilt" because it is they only way they can play, being aggressive at the Poker table does not mean being aggressive with your mouth, but they don't understand simple thing's like that.
I tend to just ignore them, choose when I want to play against them, and then hit them where it hurts, I love taking them out with better
hands, and then it's "See You Later, Idiot".
When the fun Stops, STOP!
