How prevalent were spam violations?
We cannot estimate this metric right now. We are working on new methods to measure the prevalence of spam on Facebook. Our existing methods for measuring prevalence, which rely on people to manually review samples of content, do not fully capture this type of highly adversarial violation, which includes deceptive behavior as well as content. Spammy behavior cannot always be detected by reviewing the content alone. We are working on ways to review and classify spammers’ behavior to build a comprehensive picture.
