Facebook provides an audience selector tool that is used when sharing status updates and other posts. The tool defaults to the audience that was used to share the previous post. Before posting, a good rule of thumb is to pause and review the content and confirm that the correct audience is selected. The tool is available in different areas on Facebook and updates itself for each post made. Facebook also warns users that when you post to another person's timeline, that person controls the audience that can view the post. Facebook said closely monitoring your timeline can also limit exposure to whatever your friends post to it. Trend Micro said that 36 percent of social media users say they have seen something inappropriate posted on a social network.
