A lot of adult webmasters are a strange breed. Don’t get me wrong; I have a couple of adult sites too.
When I was an affiliate manager, I had an affiliate who was a big adult webmaster who called our office and yelled and screamed at every person he could get in touch with about why he wasn’t getting paid for his traffic.
Apparently he signed up for our affiliate program without understanding that he was on rev share. He’d only made 1 sale at that point too, and I don’t know how he made it, since he was sending traffic from adult sites to a totally unrelated site.
