A trademark means nobody but you has the right to use the name in commerce. It doesn't mean Facebook is forced to give you a site (whatever that means).
Bullshit
Trademarks can't magically prevent someone from doing something wrong. That doesn't make them useless.
(No idea how this relates to Facebook, so responding to your comment generically.)
Somebody using this name claimed my site if fraudulent. Now, please show your ignorance regarding trademarks and ask how he could use the name if I have an old trademark....
