I have varied results with pimp roll, although Im just a small part-time webmaster and dont have a steady stream of traffic
with that said, I have a domain of the name of a black pornstar and I get a small amount of traffic - mostly type in. I just redirect to Ebony Dymes as of now and that converts around 1:35
I think some of their older tours dont look that great, but im not sure how they convert so I guess pick and choose.
BTW I'm designing an Adult Video Planet site for them which I think is going to be HOT - not to mention they started doing trials for AVP so its not strictly monthly subscriptions. YAY!
