I agree, but there are many threads about this same matter. It is hard for WGT to penalize quitters because there is no way to find out if they actually quit, or they lost their internet connection. I have never quit on purpose and only one time since I been playing this game that I lost my internet. I apologized to that player as soon as I could get back on. They sent me a nasty message saying I was a quitter and spread the word around that I quit. That thread has been long removed and that player actually sent a message to me apologizing.
If you are in a game with someone and they quit, make sure they actually quit and did not get disconnected. If you know for sure they quit, just block that player. I have blocked one just today for quitting on me last night. Goto ACCOUNT, next to my messages and all the way to your right click on block players.
