CPA offers with Viral Apps

Any of you trying to do CPA offers with the viral scripts? I see some are just collecting emails, some are content blocking.

If you are, how are the CPA offers going?

If I were you, I wouldn't. When people first started to really maximise out Facebook around spring time with the coming of FBML and the like, standard "Win your free iPhone" cpa offers burnt out pretty quick, and most had to shift into thinking a little more out of the box creating their own content and using gateways etc.

using gateways is the way to go but i will say one thing for sure you need to make sure you give some thing to see or read in the end other wise they are going to be very angry and that never helps
