According to
tfl.org
"A fanlisting is simply an online list of fans of a subject,
such as a TV show, actor, or musician, that is created by an
individual and open for fans from around the world to join.
There are no costs, and the only requirements to join a
fanlisting are your name and country. Fanlistings do not
have to be large sites (although some are); they are just
a place where you can sign up with other fans."
