Just out of interest
If I had been blocked by someone how would I know?
You would see their face or user name here or there -- other people talking to them in a post--but you cannot see what they write back. Or you see their face in a list of recent posts, or they liked a comment -- but if you click on their name or picture, you get a silly message that says in a very indirect way -- this person blocked you.
More to the point, would you care?
