Welcome to Spam Fighting @Scale
summary
Facebook runs spam defense at 1.4 billion monthly active users and treats anti‑abuse as a service that can cut onboarding from a year to months for acquisitions, reusing systems to fight payments and ads fraud as well as spam. The stack includes a rules DSL called Hackle DSL and an intel sharing mechanism called ThreadExchange. The talk stresses spammers are professional, exploit features like tagging and events, and false positives remain a costly constraint.
