Ok you seem confused. There are no private profiles here, it's not Facebook. Every post you write here goes on the public timeline where everybody can see it. If you want privacy you're using the wrong app. This app is more like Twitter than Facebook. It won't be changing, and there is nothing anyone can do to keep your posts private, because that's not what this protocol is designed for. I'm not "stalking" you and neither is the other random person who replied. We just saw your post flying by on the public feed. Everything you post can be seen by anyone.
