One of my favorite features about Calckey is the ability to mute words. I think Mastodon allows it, too, and I used to make use of the word filter on Reddit as well. Maybe one day kbin will include it or perhaps it's hidden somewhere I missed and some helpful person will kindly point the way.
It's great for situations like this. I use it to filter out dog posts because I have a traumatic past with them and I know I'll never convince people to quit putting dogs literally everywhere, but I don't have to see nearly as many of those posts with a good filter setup.
