Mastodon's "mute domain" is rather odd because if you try to map it to user-level action, the closest action to it is "block"; muting a domain severs your connections to people on that server too, instead of just hiding posts from them in your tl
Would love something closer to a true mute, that is, something that just hides posts from that domain in the TL - maybe with exceptions for people you follow - without severing any other connections you might have with that domain
(And yes this is apparently something that is already available to instance admins, it's just - as far as I can tell - not available to normal users)
