The reason why berating bad players is such a bad idea, aside from being tactless and obnoxious, is that you are encouragingthem to play better. if no one tells them what an awful play they just made, theyll keep on making the same mistake and eventually lose all their money. By yelling at them, not only will they realize what a terrible play they just made, they will also try to play better so they dont get screamed at again. So if you want to make money, dont clue the fishies in that they are in fact fish.
