@MegaMichelle@a2mi.social came up with an interesting and useful idea(originally for mastodong but equally valid idea for pleroma): thread scoped notifications
here's the scenario Dr. A actually knows something about topic B. Dr. A is in a thread with a bunch of dumb shits who waste everyone's time, we'll call them C D E F and G. Dr. A wades in every couple 1000 posts and says something like "no actually blahblahblah" and then goes back to lurking and watching C D E F and G talk amongst themselves what Dr. A says is actually valuable but not valuable enough to auto notify based on every thread he's in. Perhaps you're particularly interested in what he says about topic B. You could search by hashtag, or by keyword, but another useful thing would be is if the fact that he was posting in that thread itself was occurring, that you want to be notified.
Perhaps some kind of option right around the 'mute this thread' one could be 'notify when this user participates in this thread'.
