I've got two kids still in the "target range" for all these attacks. We combat with several approaches. 1) we watch what they watch and have them tell us if their preferences change so we know. 2) No YouTube, even YTkids - except on AppleTV - and we can monitor - and that's infrequent. 3) we keep them really busy on other stuff (pet, homework, family projects, outings, afterschool activities, even select videogames) This is not ideal or possible for everyone, but this has resulted, I think, in a good outcome so far.
