3 – Take advantage of privacy settings
Most social networking sites offer privacy settings, but these are often overlooked by the account holder. The default privacy level of most of these sites is set to be wide open, which allows any one of the millions of people who are online to simply look you up and see what you’ve posted. Social networking sites and other online subscription services often request certain information when you initially sign up, such as your email address, phone number and street address. If your privacy settings are not set to a high level of security, virtually anyone can find out how to contact you on the phone, over social networking sites or by email. Someone could even show up at your home.
