Creative finds side job as Facebook vandal

If you're an agency creative with a great idea but no clients willing to give it a try, why not just use it to launch a new form of Internet vandalism? That's what BBDO creative director Jeff Greenspan did when he created "letterbombing," a group effort that uses profile photos to spell out a message on a public figure's Facebook page. According to The Daily Beast, Greenspan created the concept as a form of guerrilla marketing for client brands, but he couldn't find any takers.
