You have my permission to tell us of whom you are referring to.
Asmodeus.
Famous for posting that anyone who disagreed with him and the NTSB report of flight 800 were tinfoil hat kooks and right wing wackos.
Also famous for posting "Expert noun blah blah blah" and refusing to state what his expertise was..
He finally did admit that he worked with crash investigators, whether he was one himself or not was unclear because he said that he was an "Investigator for 50+ years" one time and said "Interviewer for 50+ years" another time.
If anyone needed psychological evaluation or therapy, it would be him.
(Though I don't recommend the genius mentioned in the article!)
