I hit one recently, a ccbill affiliate program I signed up for a while back but didn't promote for some reason. So I checked out the site to see what was on it, to try to find out why I didn't promote it much.

Ignoring the fact that the tour isn't very attractive, how many holes are there? let's see.
She sell DVDs off the front page (but you don't get paid).
She sells VOD off the front page (but you don't get paid).
Her update page has all links off to other sites, nothing to her own. that includes links to her being on I'm Live, and other sites. There is no selling of her actual site, so you don't get paid.
The "Hot Sexy Bitches" is her link trades with other amateurs and other paysites. You don't get paid.
When I look at the tour, the chance that someone actually hits something that pays me is so small, why would I bother? I sent them an email, and got zero response.
