Porn site - it depends on the pictures on the site. If you're not sure, IM one of us the link so we can take a look. My opinion on that situation would be if you have the freebies on a page that is not seriously adult in nature (including any banners) and if you have a warning on the page that other parts of the site are adult in nature, it ought to be okay, but I'll also ask the other mods and admins to see if we can get a more definitive policy on that. Cheers!
