Most of them are scams ?? Yea...maybe...they keep on delaying the payment..so that got time to absorb NEW funds inorder to pay out to the OLD members...
So what will be a non scam way to build such a site using ppc ?
Plus the fact that some of the OLD members will get tired of waiting for the payment, and will give up ( and not cashing out the money they have ).
I've thought about building one, but it's a scam in the end.
I'd rather steal money from the big guys like Egay and such, than poor people on third world countries that invest their money on this kind of websites and hope to get some back.
