Witness the cautionary prankvertising in this viral spot for a Belgian bank warning you not to give out financial information online. Recounting more than just a simple case of credit-card fraud, the video shows how one truly creepy guy befriends an ordinary Belgian dude on Facebook—who was stupid enough to give out his deets in response to a phishing email—and tries to steal his life. Not content to post hilarious or insulting messages on the poor guy's hacked Facebook page, creepy bank rep has facial prosthetics made so he looks exactly like his victim, and starts posting pictures that the guy's wife probably won't find too funny. Then the doppelgänger orders an antique harp, has it delivered and signs for it, eventually appearing face to face with our our woebegotten protagonist to serious freak the crap out of him. Duval Guillaume Modem, the same agency that was behind "A Dramatic Surprise on a Quiet Square," brings the whole thing to life in a chilling way.
