The 'Hoaxer'
The guy behind this 'hoax', Tom MacMaster, was likely working for the CIA, whether he realised it or not. This is the impression I got as I was watching this documentary.
I find that other people have expressed the same opinion, see, for example - http://www.moonofalabama.org/2011/06/who-financed-tom-macmaster.html
