Speaking more specifically on sports betting. Might be bad form, but honestly me rooting for or against a players bets isn't going to change the outcome. The way I look at it is I get the same level of fun I used to when I bet on sports, but with the extra sadistic side of rooting specifically against someones bets.
I know most of the networks you can't see the players bets (at least the ones I promote mainly - RevNetwork, CommissionKings), but on old 5Dimes/new BetAnySports you can see what bets they have open. When a guy makes a huge 15 team teaser bet, it almost becomes a game of which of these bet(s) will be the one that busts it. Will he then reload and try again? Will this be the time he quadruples his money and screws my month?
Just thought I'd see if anyone else has too much time on their hands like me.
