I guess your underlying point is that a business model that sexualizes a 13-yr old is very sketchy and leads to worse things. If so, I agree wholeheartedly!
But who can tell for sure? You did not make a cogent point in your first post since people aren’t paying for these types of videos. They are watching them for free and the money comes from the ads served along side the videos. You should be asking what kind of person pays to sponsors these types of videos. I sorta agree your point isn’t refuted, but that’s mainly because it’s not coherent so logic can’t really be applied.
Anyway, I only point all this out because I think you have a good heart and the right sentiment but are losing the argument in the delivery.
I suspect this stuff is slipping through the cracks because these videos seem like normal nonsense to most people. “People watch videos of people whispering? Weird but so is almost all the rest of what other people watch on YouTube...” But apparently there’s some kind of sexualization in these videos for some people and that’s what actually makes them so popular. Very worrisome when we’re seeing children doing these videos. Raising awareness that these are actually sexual is important. I think 99% of people, including advertisers, just don’t see it and don’t realize it.
