Last year, Facebook mobilised a massive cross-company effort to protect its platforms from abuse during the 2018 US midterm elections. In this talk, Facebook will provide a behind-the-scenes look at their efforts, which included developing new graph modeling techniques to identify coordinated attempts at manipulation, new systems to combat voter suppression in real-time, and new transparency requirements to bring more authenticity to political speech. They will also outline some of the tough challenges and open research questions that remain as they take on increasingly sophisticated adversaries and try to scale these civic integrity measures to elections around the world.
