When you block a user, your replies to that user should be deleted.
It's become very common for people to weaponize the block feature by posting something inflammatory in reply to you, and then blocking you so you can't reply to them. That allows their words to remain the last statement in possibly a long running argument. It would reduce the ability of the feature to be weaponized if, when you block someone, any comments you made in reply to their comments would get deleted automatically.
