>People figured out how to game Youtube's search algorithm>Said way to game the algorithm involves using characters incredibly popular with children>Little kids are curious but don't have a bullshit filter to see that this stuff is garbage>Low quality videos are able to get pumped out on a regular basis and garner billions of views>People who do this literally make millions off of it and aren't going to stop anytime soon>Can't say for certain why there's so much fetish material or dark violence, but the people making these videos may have a kink for that kind of stuff.
