Some years ago I was banned by him after some comments on his YT videos. Yes, the guy has invested a truly enormous amount of time and energy in this conspiracy position. Let alone all of his ego. The guy really committed himself publicly. Most likely he started several years ago with a naive belief and sincere doubts, based on ignorance and distrust (a political agenda?) that the NASA Apollo Moon missions were faked. And of course he studied a lot more about space travel, unfortunately visiting mainly hoax websites and reading conspiracy books, and just when he came deep into the specs and details of Apollo he must have had second thoughts. Also, many credentialed people have patiently explained many of his stupidities and errors, in great detail (some of us commented on his videos about radiation effects, his 'revelations' about Apollo photography, math and physics calculations, and the capabilities of the Apollo computer, and many more things). I think he feels it's too late now. There is no turning back for him.
