I would just interject here that looking at the sites listed in the recommended area or some of the sites listed in the regular links could be a little misleading for the non-initiated:
Linklists tend to list sponsor hosted sites and other links to their own free sites as well as friends (that link to Tommys was a good example) as well as the "standard submitted free site"
Where you are going wrong is that there is a set "template" for free sites submitted to linklists that takes a little research to find the definition of - but simply put - a free site for submission consists of a simple warning page, a main page and two galleries or so - the recips are not required to be on the warning page although evolution of the free site game has pretty much put them there - I still get a few submits every day that have them on the main page and that is not a problem
The type of sites you want to submit your site type to is the adult search engines, directories and toplists - but it really does not fit a linklist (unless you start your own and list your own sites
)
