Artemis has this, currently the overall app is in beta & you have to be using an account from artemis.camp (until the kbin api is fully rolled out to all instances)
I’m not, however, a fan of people who comment just to complain about seeing something they don’t like instead of curating their feed or moving past. Which is why I’ve said nothing to the folks wishing for proper block/mute functions (even though a random post really isn’t the place where that’s gonna do anything; spend that energy making feature requests or in communities for those upcoming apps where the devs will actually see it) and made the comment to get person snarkily complaining about Musk content.
