Many users do not desire to interact with underage users for many reasons. Some underage users may wish to opt out of seeing 18+ users so they may bond with people closer to them in age or perhaps for safety. I think a functionality to
- mark your account as 18+
- hide content from accounts who didn’t mark self as 18+
- hide content from accounts who marked self as 18+ would be very useful to those users and set a higher standard of personalized experience for users engaging with social media.
There were a bunch of smaller social media platforms I’ve been on around 2016 that did the separation for age and it usually just ended up with 18- marking themselves as 18+ and vice versa. I can’t remember the name for it. I think one was called teen network or something. And the other one was a mobile app with a blue target logo.
