These sites are not scam. They do pay, but it is very difficult to get some downloads, because of the surveys. Many people just can't complete surveys.
They pay from $0.25 to $16 per download. Every Site pays different...
Hope i made things clear.

You are talking about different site type.
I don't want to promote anything, but i'm talking about sharecash type sites. I think they are called PPA (PayPerAction)
