@bri_seven @caffeneko @llebrun I can definitely see where that could be an issue. Do you think the review concept is not feasible?

Maybe have users authenticate through their instance? Bad actors create multiple accounts

Minimum account age? User has a single post and then wrongful ban

I do not have many ideas to ensure that only valid reviews are posted and marginal communities are not punished.

How much privacy/consent is expected while posting publicly?

That being said,
Preferences -> Preferences -> Other -> Posting Privacy -> Followers Only
