I posted this in another thread, but I don't know if anybody saw it. So, to make sure more people see it. I'm sure most of you know about this, but i know there are some of you who don't. Do not post a picture to facebook or any online media from your cell phone or anything that could possibly contain your location. It contains EXIF data that will show the coordinates of where the picture was taken. With that little information, they have greatly narrowed down your whereabouts. If they have even your first name, they could start doing a search for your first name in the relevant area of the coordinates on facebook and find you. From there, they will gather all the information that is there, which includes full names, phone numbers, email addresses, pictures, and your wall posts, depending on security settings. Now, if pictures are available to them, they could learn from how you are, whether it be that you party hard, rich, poor, or just sit in front of your computer all day. And if you have a picture where you have school t-shirt or sweater on, then they now know where you go to school! So, they now have your full name, school you go to or have gone to, know what your friends look like, phone number, and know exactly what you look like. They could wait for you to leave the school and follow you to your home. Now they know where you live. If they wanted to, they could kill you, rape you, rob you, whatever they want. Long story short, never ever ever ever post a picture on a public place from a cell phone or anything that could contain X and Y coordinates in the EXIF data in it. If your phone has location services, turn it off unless you are using a GPS or an application absolutely requires it.
