Making bets then stiffing people because you don't like them isn't acceptable and especially so on a gambling forum. No one is forcing you to make a bet with someone...you don't accept a bet and then say "nah I'm not paying" you're simply an idiot.
Not paying you because you're a ghost is completely valid, even if you disagree. I'd probably pay you in this situation, but I don't hold it against Jdeuece if he doesn't pay you.
