Yeah, from my experience the guys who spam the chat room have very little skill in game.
I had one guy who kept writing "fight me 1v1 b******" so I challenged him. He picked Sektor and spammed teleport, so after wiping the floor with him, he chose Kitana, I was Kitana aswell so maybe he wanted to rub it in if he won? well needless to say, he spammed the fans over and over, he then received a 46% combo and quit.
I love MK
