Fanlistings are sites that list fans of particular subjects. In this case, this is a site that lists fans of the relationship between Batman and The Joker. In order to be listed as a fan, you only need to put your name, email address and country. If you own a website and would like to include that link with your information, you are expected to put a link back to this site, somewhere on your site. If no link is found on your site, we will only list you with your name, email and country. (You can opt to keep your email address hidden from view.)
