Not sure what it means, but there was a yellow bar at the bottom that had that statement on it. Had to click the start button to override it.
Usually people make them unlisted when they want to limit who sees it. That way it won’t show up in searches, etc. If it’s posted somewhere on a website, that makes the potential for a broad audience much higher. Your friend’s soon would have to define why he did it that way.
