So for instance, let's say you've given up on meeting Prince or Princess Charming in the real world and you've turned to dating sites. But you know there are some bona fide crazies out there, so you'll want to play it safe. For your profile pictures, you're sure to only use photos without recognizable background features or tell-tale scars proving you're the Chosen One or a Cuban drug lord, because then anyone could find you. You don't post your real name and you keep all your personal information behind a privacy wall, which is like a chastity belt for your identity, if your identity were a vagina.
And creating a Facebook profile is like vajazzling.
Little do you know that the innocent self-portrait of you in your favorite George-Washington-but-as-a-cat costume has led Glenn Close (or her male equivalent, also named Glenn Close) right to your door. That's because every digital photo has a wide variety of information stored in the actual code of the file: Time, date, camera type, camera setting and how drunk you were when you took it are all embedded in the file when you upload the picture. You know what else is in that file? If you used your smartphone, the GPS coordinates of where you took the picture. You might as well arm your stalkers with some roofies while you're at it.
