www.linkspun.com is up to 600 webmasters/users and well over 15k pages added in 120+ niches. I've got some webmaster/affiliate ad spots that are shown to webmasters building and running sites in the niches of your paysites.
Below are examples of the ad spots, 2 are shown at the top of all category and search page, and shown to relevant affiliates for that niche. Blowjobs (top 2) and the Pornstar (bottom 2) category spots (thanks FYC and Blazing Bucks). These categories are browsed by webmasters daily in search of trading partners in this niche and checking page info, outbounds etc on existing trades.
These ads are static, they are yearly, first come first served, and they are $200 a spot. I allow and encourage them to be updated with new sites, new promos, or program news as you see fit. Keep them fresh and you will get more notice from webmasters (we are a finicky bunch) and the ad spots become a resource both for you to showcase your relevant sites, and for affiliates to see whats new and upcoming in their niches they run.
This week I'll be offering the following deal to fill out the category base:
4 Category spots for the price of 3. - Advertise on any 4 niches for a year for $600.
