I feel like blocking someone should make it so they can’t see your posts or respond to them at all, and at the very least so you can’t see anything they respond to or include you in without it being your choice. Right now, it’s almost the opposite. You can’t see their comments, but they can still see and interact with you, and the system lets you know they have, but leaves you with no way to react other than unblocking them. That’s not at all how it’s supposed to work.
