When I started with free-sites I did the same thing with a very similiar site, and I still get search engines hits for those results.
You'll get more traffic and more universal approvals from your own purchased content. You can get listed on the big sites using
some sponsor content, but it's kinda like Russian Rullette to see if they list it.
Small link lists will most likely list the sponsor content, but you're not going to see the raw traffic you will from the big guys.
One thing I benefitted from was putting a lot of detail into the description, like the model name and maybe something she's famous for being in or doing. A surfer would search for the model name and get the linklist as a result and then find my description. The surfer would then hit my link and get through to my site, looking for a specific model or site he was looking for in the first place, very targetted.
Food for thought. Good luck.
