Sorry to say this, but if you don't like it, just don't play. If I am going over to a friend's house, and they offer me a FREE home cooked meal, whether I like it or not, I was raised to say thank you very much and to never bitch about anything. You need a serious attitude adjustment.
Not trying to be a jerk. Just offering an opinion. Guess that's not a good idea. Who cares how many posts they have? It's all about exposure for your site and this site isn't it? Isn't that why you have the contest? To get more people interested in your site(s)? Naturally that's going to draw more interest besides regulars with 5000 posts. That's why you have the contests in the first place. If McDonalds was giving away free food don't you think more people would go there besides the ones that normally do? I still like playing, no big deal, but bascially if someone has the same picks as me I've already lost the contest before it started if they have more posts. Obviously you have to do picks you don't want then to have any chance at winning.
