I always warn people about the kind stuff they post on their Facebook, Twitter, or Instagram. And this guy is the reason why. Comedian, prankster, and YouTube filmmaker Jack Vale; he decided to go to a busy area in Irvine, California, and figured out how to find the most-recent stuff people nearby him posted publicly on Facebook and Twitter. Then after he read their posts, he found the people, and messed with them by pretending he was psychic.

Moral of the story: Be careful what you make public because you never know who is stalkin' or creepin' around on your or your social media pages.
