Screw over Meta then. Not everybody else.

Meta is the bozo in a panel van with no windows. All The legit porn sites put up Big Blinking Neon Signs.

I actually run an adults only community site and you are correct, I have it in a popup that appears on every "fresh" visit to the site, it's in the giant bold print you agree to when you register, and from a technical end, I send every possible header and other signal to let filtering software know it's an adult only space. If there is a child accessing that site, they are doing so because their parent didn't even attempt to prevent them from doing so. And now I'm having to look into ID verification services that are going to quintuple to costs of hosting this free community for people in a time where community is more important than ever.
