If you would read correctly, you'd notice that you don't specifically have to "buy" your ads. You can earn them. If you "read", and gather some information about the program, you'd see that there's no participation fee, and the more websites you view yourself, the more "noobcash" you get, which you can use later on to "purchase" ad credits for your site. So, where are you getting this having to "buy" ads? Read thoroughly, and it could benefit. Trust me, if it was a scam, I wouldn't have registered for it, nor be using it. But hey, your loss.
