Take a look at my site and see if you have a site that falls in one of the niche categories.
http://www.TheUncensored.com
It is a top list, with rankings is based on productivity, not IN (which you need to take note of when you look at the categories as you wont see an IN or OUT). On average I send back twice the visitors I get in. Anyone listed will tell you how productive my traffic is. I don't use blind links or skim any traffic.
If you want to get listed, you can go to the link in my sig or hit me up on ICQ (though the site below is faster).
