The FBI spent years investigating
an anti-goth cult that didn’t even
exist. After a worried goth contacted
the FBI about the ‘Church of the
Hammer’ and their Yahoo group
‘GodHatesGoths,’ concerns grew and
the Bureau launched an official
investigation. It continued for over 2
years before they realized the entire
thing was completely fake and intended
to be a joke – which had been written
as a disclaimer on the website all along. Source
