I’d be wary of YouTube comments sections, if you scroll long enough you see a lot of comments, even more intelligent sounding ones, repeated several times.
I usually stay in the tech help of YT; “How to clean a leaking toner in your LJ 4000.”
The other day the comments suddenly turned into a troll war!
“Chum, if your mother says she loves you, check on it.”
And I would add: know the source.
