Could you please stop posting uncivil and/or unsubstantive comments to Hacker News? You've done it repeatedly, it's not what this site is for, and we eventually ban accounts that do that.
Age control isn't a legal requirement for websites that host porn in the USA as far as I know. Google, for example, will return porn in image search results (if you disable the safe search filter), and you don't have to verify your age first to do that.
And you're right, it has always restricted illegal content. And that's a good line to draw.
So..
What's illegal about this new content?
Or what has changed that they now think they're ready to judge what is extreme and hateful?
Or what has changed that they now think they even should?
