The only one we have so far is that we blocked YouTube at the router level. YouTube (and YouTube Kids etc.) is down-right creepy when kids get hold of it. The kids will watch things like Netflix or Amazon Prime for a bit, get bored, and do something else. They'll play stuff like Minecraft for a bit and move on too. But put them in front of YouTube and they will sit there all day watching banal, repetitive, shockingly…
That's super weird. Have you tried to figure out what the difference is? Netflix and the like also have a lot of the features that I can think would cause such a reaction: infinite playback without user input, very little friction from opening to playing something and so on. Is it the content? Or what it recommends? Might give a reason to why kids seem to be hooked to elsagate videos...
The content the kids get hooked on is sometimes down-right weird. My older daughter got hooked on this Minecraft YouTuber called Preston who just yammers for hours at the speed of an old fashioned auctioneer. It's utterly obnoxious to grown ups but the kids will sit there until they're in a puddle of their own urine. A neighbor kid got hooked on weird "meme videos" full of pictures from horror games set to banal nursery rhyme style music. They got obsessed with characters from a game called "Five Nights at Freddie's" even though they've never played it. Some of these videos are 12 hours long and obviously assembled by bots.
It's fucking "kill it with fire" creepy. It's so extreme with kids if I didn't know such things were impossible I'd start wondering about 5G mind control conspiracy theories. (Alas, the link is WiFi not 5G...)
Other parents have told me the same thing. I've helped a few neighbors ban YouTube on their routers. I've read it on parenting forums too.
I've heard TikTok can be this way for teens but have no direct experience.
