No idea, honestly - not a trekkie, so I never cared enough to ask :)

I’m on an instance that defederated from only 3 other ones: voyager.lemmy.ml, ds9.lemmy.ml and enterprise.lemmy.ml - just checked now. I honestly dont see a firehose of trash, tankie invasion or anythig of the sort. I do aggressively block communities I have zero interest in, so it might still be happening there, but I personay don’t see it at all - anecdotal evidence, I know, but that’s been my experience.
