Ummmmmm yeah. That's kinda the point. You haven't played this game long, you will see. When you get to higher levels your goals are to win thousands of challenges. I need to win 5,500 challenges now. You just go down the challenge list and click challenge on every single person. I don't even pay attention to what level they're on. It's not necessarily for the fun of seeing who wins anymore. Most people just accept because they know that when their time comes around they will need the same thing. And for gods sake its not like it takes much of your time to click accept and it certianly doesnt hurt you at all. But if you dont want to accept it then dont lol.

LOL I didn't challenge you for bd it was just a challenge thats how the game works- you were on the challenge list.
