Inspired by prankster Jack Vale’s Social Network Stalker prank, BuzzFeed took to the streets to freak people out who are lax with their online privacy.

A BF team member asked passersby on the street for a quick interview. Once he had their name, a crew of Internet nerds in a nearby van searched for any personal info they could find online and fed it back to the interviewer via a hidden earpiece. 

Naturally, the interview volunteers were creeped out by the “Facebook stalking in real life.” 

“Wait! How’d you know that about me?!”
