The biggest surfer forums with the most traffic are all about stolen content. If you are trying to sell a paysite membership off of one of those...good luck. I guess you could put up a dating or webcam ad on them.
I monitor some of the biggest ones in the world just keeping an eye out for our content, and those things are just page after page after page of torrent links. Pretty much every major programs' sites completely ripped.
I would suspect it would be kinda hard to sell a membership to a paysite to communities that are built around who can post the most links to stolen content.
