You won't be able to curate everything forever, so in the long run it's easier to get them asking questions (and to ask them questions) about what they're watching. They'll quickly be able to tell what's trash media on their own. Advertisements were a big problem in our house at first. Every toy was enticing, but the fast cuts and up-tempo music made them look more fun to play with than they actually were. Have you tried asking them about motivation? Like, those YouTube channels you don't want them to watch were made deliberately, but for what purpose? Making something forbidden doesn't make it any less misleading, you know? It's the ability to question it that takes away that power.
