Yeah internet is weird enough, however it gets even weirder when algorithms start affecting what people make.
For example that channel where they did the n-word baiting of black people as a "prank" suddenly changed into a channel where Spiderman and The Joker have funtime adventures with Elsa and Anna from Frozen (SFW stuff), and subscribers of that channel tuned in and were all "WTF is this shit?". And you can find dozens of completely unrelated channels which make a constant stream of videos Spiderman and The Joker (occasionally Superman) have funtime adventures with Elsa and Anna from Frozen. And if you stumble on some of these channels you might wonder why it's almost always those two Frozen characters vs Spiderman, the Joker and Superman. The answer is because of youtube algorithms. People worked out that this combination of keywords gets you the most hits on Youtube Kid's autoplay feature. And stuff that gets watched merely reinforces the keywords involved, so all variety gets weeded out. So that's why dumb "prank" channels all turned into Spiderman/Joker/Anna/Elsa channels all of a sudden. They just abandoned their teen/millennial subscribers completely chasing those sweet, sweet toddler autoplay dollars.
This stuff isn't even memes. It's way less cool than memes.
