So you want your kids to be able to watch youtube without supervision, and you want youtube to be responsible for the contents, and you're not bothered by dangerous DIY videos, "viral pranks", very violent movie trailers, etc., but you're afraid they'll see, how they were created?

Kids should not watch youtube unsupervised, never. I know Elsagate is a conspiracy theory, but those videos are fscking inappropriate, and come as recommended content for kids, and youtube allows that already....
