Actually had this happen the other day on Facebook.<p>Unfollowed a friend due to some strain on the relationship, and just needed to avoid them temporarily and didn&#x27;t want to see anything from them. They shared some of my content, which placed them in my notifications.<p>Notifications can only be marked read, not deleted, so it was somewhat stressful. it&#x27;s a very minor use-case, but there is no remedy but to get other interactions to force the notification out of sight.
