No matter how you package it or re-package it, revenue share sites are all scams. As tempting as they may be you'd be much better off buying actual investment products... stocks, bonds, etf's etc.
My experience has been about the same. Most of the traffic I got through fivver was extremely poor quality or bot traffic. The only real traffic I received was via someone posting to their twitter following. I think I got 7 or 8 hits. Not a great value for $5!
