As a phabricator user who follows notifications, I want to be able to unsubscribe from reports which I do *not* want to follow, without being re-added unless considered necessary by a human, so that my notifications contain what's relevant for me.
What happens instead: I remove myself from a task https://phabricator.wikimedia.org/T76356#823765 and a mere reply adds me again https://phabricator.wikimedia.org/T76356#823886
