And as always, kids will find a way to circumvent restrictions no matter how the state will try to enforce. South Korea is a prime example of this - they had a law starting from 2011 where kids can't play online games after midnight. After the enactment of the law kids began to use other people's IDs (parents, older friends, ...) either by persuation or resorting to more "sneaky" methods, making the whole thing kinda pointless. The law was eventually abolished a few days ago.
