Weibo can limit the scope of certain content or news. The user can choose to set certain content or messages to be public or private. Public content or messages can be seen by all followers, while private content or messages can only be seen by followers. If a user didn't follow anyone, they could only see the content or messages that they had set to be public. If a user wanted to check the private status of a particular content or message, he or she would need to pay attention to the content or message's sender and then set the content or message to private. It should be noted that if a user sets a certain content or message as private, the content or message they previously posted will no longer be public. Only the people they follow can see it.
