This isn’t the simplest solution, but…
Yes, you can go into preferences and add users to your mute list, but what about people that you just want gone gone?
If you know how to wrangle CSS, you can do so by adding this little gem:
article[data-user-id="####"] {
display: none;
}
Replace the “####” with the user ID of the person that you can’t abide.
If you want to know a person’s user ID, it’s in the HTML of the page, just dig into the source and find the article header:
article id=“post_##” data-post-id="######" data-user-id="###" class=“boxed onscreen-post”
Once you add this to your favorite CSS filter system (Greasemoney, etc), that person’s posts will be toast.
