We do continue to grow in size, but we are also constantly challenging ourselves to develop in such a way that every employee focused on security has a greater individual impact tomorrow than that person did today. We can do that both by continuing to innovate on our approaches to security and investing in system and infrastructure.
Fortunately, we reacted quickly and have had success beating it back. In addition to improving internal detection mechanisms, we have worked with browser vendors to make it harder for spammers to take advantage of this vulnerability in the browser, and we have partnered with external companies to make our malicious link detection system more robust. We are still battling this but thankfully it is much less of a headache than it use to be.
I can't remember the last time I saw a bogus or information-collecting app being pushed onto users by third party developers, and I recall them being plentiful at one point in time. How did you solve that particular problem?
We have several different teams that work closely together to ensure people have a great experience when connecting with applications that leverage our platform. Major props go to the platform integrity engineers who have been constantly iterating on the automated systems that we put in place to secure our Platform. Of particular note were the changes we made last July which made significant improvement to the enforcement systems so we can identify and disable apps that violate our policies as quickly as possible.
These changes instituted granular enforcement which selectively disables an app's ability to propagate through Facebook based on the amount of negative user feedback - so that an app that has been reported for abusing chat will have this feature disabled until the developers have made substantial changes. In the future, we are moving to more sophisticated ranking models where the amount of distribution will be a function to the app's quality. Good content will be seen by more people, while lower quality or spammy apps will be seen by fewer people or no one. We believe this will reward apps that provide great experiences while minimizing the negative impact of poor quality apps.
