@Sir_Boops I can actually explain this. People pump out a shitload of formulaic videos and take advantage of YouTube's tagging system to ensure that the videos all feed into each other.
This is to exploit the ad revenue to be gained from children who are given a tablet device and watch YouTube set to autoplay.
Elsagate is a thing. It's basically people doing the same thing, but with really fucked up videos, like different movie characters in perverted or abusive situations.
