I'd just get over it. It makes him happy. It's not really an important issue at best slightly annoying.
The problem Jon is that proper researchers use Youtube and come across his drivel.
As David said, the researchers wouldn't be doing a very good job.
Agreed, but when these things are presented as fact - he's steadfastly refused to do as any sensible user would and label this drivel as a mock - it's simply misrepresenting history. As has been discussed at length via Transdiffusion, nobody would bother if a) he wasn't stealing clips and claiming them as his own - to the extent of trying to have the originals removed and claiming animations created in this decade were magically broadcast on S4C in 1985 - and b) if he'd just make it clear that it's not real. When he genuinely seems to believe his own lies about being a
CA, and presents fallacy as fact, whether or not researchers are stupid enough to believe him or not isn't really the point any more.
There's only so much any disabilities or difficulties can be used to excuse that behaviour, and indeed his appalling overtures to so many people online.
EDIT: At last, I see his YouTube Channel has the word MOCKS in it's title, and the most recent video describes the junction as "recreated". Well, it's a start. Just another 1,845 video descriptions to be edited to point out they're not real.
