People with odd names are having trouble signing up to facebook, according to The Washington Post.

Caitlin Batman Shaw, mental health therapist from Virginia, says she was unable to add her maiden name, Batman, to help old friends find her. Facebook admins thought someone was having a laugh and simple rejected the change. After three weeks of emailing Facebook, the powers that be realized the mistake and let Batman Shaw use her maiden name on the site.

A Facebook spokeswoman says names such as Batman get flagget automatically because the number of real Batmans is probably "fewer than the number of people who could potentially misuse the name on the site."

Other names flagged by the site include Yoda, Christmas, Beers and Pancake, and some avatars are also disliked by the site.
