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.
Exactly. If it's just a checkbox (I'm a minor or adult), it's clear that there's no authority verifying anything and that it's just a filter. That has value, just like the "Bot account" checkbox that lemmy has.
It's not perfect, but it's easy to add and likely brings enough value to be worth doing.
