Why is it very important not to give out personal information on the Internet? If you share personal information on the Internet, it puts your safety at risk online. People that view your posts know your personal information including your full name, your location, your schools, where you hang out etc. There have been incidents of victims being tracked down because they shared too much about themselves. This is why you decide up front how much you are going to let people know about you. Even giving out a password for any reason, is a no-no because people can find some important stuff about you things like credit card pins, adresses, pictures of yourself or family. Bottom line is don't give out any important information on the Internet.
