Lemm.ee is the best of the lemmiverse imo. Rational, communicated choices where the users are expected to make the final adult call.

Given that sunaurus has explicitly declined to defederate from unpopular and highly-blocked instances, stating that disliking content is not a reason to invoke defederation, I’d have to say this is the least-censoring instance I’m aware of. At least at the admin level.

At the community level, communities can moderate and censor themselves however they like, but I certainly can’t think of any examples I’d call censor-heavy.

Lemm.ee is pretty awesome and allows me to browse the lemmiverse basically uninhibited. Could not be happier with how it is run
