If you haven’t joined the community, you should see this button to block it below where the Subscribe button is.
My ADD is on full swing because I’ve been on Lemmy for the past month and never noticed that button until you mentioned it (although in my defense, it seems sometimes that button shows up as plain text, not clickable - apparently another UI bug). I finally blocked some silly communities that tended to show up on the “All” listing.
after typing that last edit, I see that the original question was asked 9 months ago.
Probably something to do with that bug of very old posts showing up at random on the “Hot” sorting.
