Anyone use pay per play?

Anyone use pay per plays such as sellingppp and netaudioads?

What are your experiences?

Anyone send cheap traffic to their site with the ppp code in it (maybe junk) and still got paid? How much? (Please share)

I want to put ppp on my blogger and so I don't know if it's beneficial or not. Tell me your thoughts.

P.S. I didn't find a forum thread on this topic after May 2008, so I need help.

would someone please help me out??

dude I have used PPP and my experience had been pretty bad. first of all my visitor count dropped drastically after putting their code and the number of impressions that I used to get per IP also reduced drastically. There were some visitor who even commented on my blog that they find the audio very irritating and I should take it off.
When I checked my account with them I found that even after 10,000 impression I have only made $0.20. I personally think its not worth the effort.
