Okay, I agree with tossing sitters from Freerolls, BUT...
Why toss a sitter who paid to be in a tournament? Come on, if you can't outlast a player who folds EVERY hand, who is the problem? You need to ask yourself why you play the game. Sure, you're gonna get bumped early every so often. But having someone at the table who folds every hand is only to your advantage. They add to the pot while never taking it. You know their action every hand.
Ignore the sitters and get on with your game. I don't mean to sound harsh (and no, I'm not a sitter), but if that's how they want to play their chips, let 'em. Take their free chips and make your stack grow. Any winning player should appreciate the stupid sitters at their table.
