Except for the countries that have anti-hate laws that are deliberately vague and specifically used to jail anyone who is disliked by the government. China and Russia come to mind as examples, but I'm sure they aren't the only ones.

Besides hate-speech, I'm not sure how much should be censored really. China does a lot of censoring to 'protect' their citizens from everything, I'm not sure this would be a good thing even if that really was a goal.

And protecting children from traumatising content looks like another good thing to do, but under that banner I usually see governments doing whatever they want without caring about children past using their image.
