Not sure if this is a planned feature, but not being able to block instances. I can do that on Mastodon so I expected to be able to do it here as well. Outside of the usual extreme cases where defederation makes sense, that would solve a lot of “lemmy.deez user said this! why doesn’t lemmy.nuts defederate from them?” bullshit. Of course there’s always the option of changing instance but you’re never gonna agree 100% with the owner’s choices when it’s something you should be able to have control over.
