Am I correct in assuming that blocking a community stops it from showing in your feed? I see a lot of posts from communities in languages I don't speak and would like them to not show up on my feed. So I blocked a few, but I'm not 100% sure if what I did has the intended effect.
(Maybe it's just because to me, blocking a person seems like something I wouldn't do to someone who hasn't done anything wrong, haha XD)
With kbin you can block the instance, with Lemmy you either can a) block all their communities (subreddits) or users b) ask to get blocked by their mods or admins or c) hope your instance admin defederates them.
As someone who wants to block certain communities out of my life, like say conspiracy Q ones, I wasn‘t able to stay on Lemmy as long as we don‘t have that feature. Hope they‘ll add it eventually.
