How do you keep a system with 1.3 billion users (mostly) spam-free? This talk will describe some of the biggest challenges in spam fighting and security at Facebook, as well as going into more details about one specific mechanism - our system for detecting and classifying bad urls on the site - and how we use it to prevent attacks.
