I now have a second person muted on micro.blog
The first was someone who posted a lot of cranky and rude replies to people.
This second is one I thought I just didn’t need to read (it’s almost all “meta-writing” about tools they are trying, etc. but never has anything to actually say) but they keep showing up on Discover.
Not sure if muting them will clear them from Discover RSS. May need to give up Discover.
