Denial for sure. What he's probably doing is getting desperate and playing trash hands to pick up chips thinking somehow they are unbeatable. So of course he runs smack into a real hand or a bigstack limping with almost anything and either hitting or bluffing big enough to scare him off his pot.
One mentioned about making people redeposit..we're talking freerolls
here. As for making people reload, that's just silly. The sites make their money off of rakes, not deposits. The more hands a person plays cash hands the more money the site makes, pretty simple math. (btw, that's where money of fr's come from with the exception of sponsored games like CC freerolls where this site pays the prize money to the game site to hold the games in our name)
