10 THINGS YOU MUST NEVER PUT ON YOUR FACEBOOK WALL PHOTOGRAPHS OF YOUR CHILDREN: While it might seem cute, putting up photographs of your young ones could expose them to pedophiles. Also, what type of information or pictures would your children want to see about themselves online at a later date? PHONE NUMBER: Your privacy is important, so unless you have a phone number for business purposes, putting up your personal number online could lead to unnecessary phone calls, stalking or even being exposed to scammers. LOCATION: There are location services on Android or iPhones, which means that many people know where you live including those that may wish to harm you. Please turn off your location.
