Okay...
Just saw that, this is either a bug, he stole someone's cash, or he hacked.
Because with the amount of posts he have, its impossible to make 99K (Counting that you get 5 dollars with each post).
Also...I dont remember he had any kinda store, or something...He neither could have played those Quize's as they're not working (Fix 'em goddamit!).
So either...He stole some other member, or hacked himself to get money :/
