...and the OP allowed him to freeload the entire game. ..and there was no "clear message" delivered. There is a difference between setting boundaries...and taking retribution. A difference between not allowing one's self to be taken advantage of...and looking to punish or harm someone else. The OP was not setting a limit or protecting himself. He was looking to punish this guy. To do what he did had nothing to do with any sort of "message" other than to be vindictive and cruel to someone doing somethign he didn't like. If he wanted to make a statement, he either needed to boot the guy right away...or (as another poster suggest) send him a warning message that he either needed to participate, or he would get booted without any rewards. So it THEN becomes clear why he's getting booted at the end.
