I believe there was recently (this year) a big furor in the right/alt-right about this sort of thing, except it went much deeper, somewhat a la "Pizzagate". It felt very conspiracy-theoryish. I didn't read a whole lot into it, since it seemed pretty crazy, and the videos linked were, admittedly, pretty disturbing.

I now wonder it there's really something to this, especially with regard to people intentionally messing with/traumatizing kids via these videos.
