Bullies, burglars, and bad guys
Facebook is a potential treasure trove to the criminals and con men that lurk everywhere on the Internet. Every piece of personal information you post online is another building block to your identity. Your name and birth date are passable forms of identification, and the name or location of your elementary school might be the security question you picked when you registered for online banking. Your friends are eager to hear about your vacation, and you’re eager to tell them, but posting the details of when you’ll be out of the house is an invitation to have your windows broken and all your stuff redistributed through the secondary market.
