For the online safety thing, if a minor is going to use the Internet, generally, it'd probably be best to do it anonymously, and to leave no connection to their actual identity. Even if they trust someone, there is no particular reason to say more than should be said.

Frankly, I don't like these real identity models (I don't think this was a thing back in the day, or not as much of one). If someone is going to do that though, they should only communicate with someone they actually know, not some random person on the Internet who has appeared out of thin air.

It is also interesting that some of the most censorious platforms, as far as sexual expression is concerned, have some of the biggest problems. It's as if blunt censorship doesn't actually stop predators.
