Block feature shoud go both ways. If, for example I block someone, I see them gray, but they are still able to see me. The purpose of blocking someone is to keep them out of our lives. If they can still see us, then this block is half achieved purpose. It should go both ways. If one block someone then both avatars should be gray. I have a friend that blocked someone and he can still see her and follow her in her usual spots. She sees the view crosses fixed on parts of her body even though he is blocked. This is making her uncomfortable and should not be allowed. Blocked people should not be able to see the person that blocked them. Thank you
