@feditips Mastodon's latest update (4.2) has two great new ways to handle prolific boosters.
1. Filter out boosts on their profile by selecting the Posts & Replies tab to display posts & replies but NOT boosts.
2. Separate prolific boosters from your home feed by adding them to a list (I have a list called Boosters). Edit the list by clicking on the toggle to "Hide these posts from home." You can open your Boosters list at any time to see what you've been missing.
