Nature abhors a vacuum. Banning social media for kids with inattentive parents is the path to porn. If anything, a child who gets no wisdom at home at least has a chance of finding some on social media. Happily it seems youtube without login will still be available. We'll see how it looks in practice; declaring a thing isn't the same as making it actually happen. Hopefully Hive gets some attention. Nobody to threaten or fine on a decentralised blockchain.
I don't think most do. There is little wisdom where the kids seem to be spending their time, and without guidance, the wisdom they might get is probably missed.
I don't think the ban will work for the most part, I just hope it makes more parents pay some attention.
