Bookmarkers
 

Why do link lists want bookmarkers? Seems to me bookmarkers are free loadin' bums that want to keep looking at free porn. Is the idea that some day they might buy something if they come back enough times?

Bookmarkers are surfers who trust a certain link list / tgp and they regularly go to that place because they know they can get quality porn from and they don't tricked.

They're not free loading bums. Some people are sceptic at the begining and they won't jump on signing up to a paysite from the first visit. So, if they bookmark the site and visit it a few times without getting tricked or something, they get to a point where they feel secure to make the step to joining a paysite.

... and possibly joining another site later, when they're ready for a new flavor. |thumb

Yep, bookmarkers become repeat customers!
