If a user (Stamets, for example) is banned on your instance (startrek.website, for example) even here, a community on lemmy.world, you can’t see his posts. Not only that, but if he comments you can’t see any replies to his comment. There are a lot of comments in this thread startrek.website users can’t see.

Jeez, that is…wow. A shitty mod can really wreck content visibility on the 'verse if they’re feeling particularly shitty.
