So I've tried updating this with a long thing but I feel like I'm just making rules to have them and not really wanting them, so, probably final word in for now.

Do: Have your pronouns and age (range) on your profile somewhere.
Don't: be a minor or interact with minors as an 18+ account.

Aside from that, it's just however I'm feeling at the moment. Maybe that's fickle but idc, it's my account I do what I want.
