You can Ignore, Mute or Hush a user.
Ignore: Their content will never make your feed. You don't have to see their posts.
Mute: They will not see your content in their feeds and even if they did, they cannot comment on your posts
Hush: Anyone you hush's comments automatically filter to the bottom of any comment feed.
What's cool is that this curates your experience with this user. However, in the same feed where you have a user hushed, they may be at the top of someone else's version of that comment thread.
There's no doubt that we will continue to have new functions and features etc as we need them, but this is where we find ourselves now. If you stick around, you will find that we are constantly adding new functionality, much of which is suggested directly from the community.
