Lemmy is having some stability issues across its instances because of this growth curve: https://lemm.ee/pictrs/image/693866c7-8f65-4046-8781-58aee70...
edit: Nevermind Safari works. 1Blocker blocks comments with the "Block Comments" ruleset. Usually it is supposed to hide comments where they are not the primary focus. So some rule should probably be adapted for Lemmy instances to work.
