"The Courage Against Hate initiative has been brought together by Facebook for the purpose of sparking cross-sector, pan-European dialogue and action to combat hate speech and extremism. This collection of articles unites European academic analysis with practitioners who are actively working on countering extremism within civil society. Hate and extremism have no place on Facebook and we have been making major investments over a number of years to improve detection of this content on our platforms, so we can remove it quicker - ideally before people see it and report it to us. We’ve tripled - to more than 35,000 - the people working on safety and security at Facebook, and grown the dedicated team we have leading our efforts against terrorism and extremism to over 350 people. This group includes former academics who are experts on counterterrorism, former prosecutors and law enforcement agents, investigators and analysts, and engineers. We’ve also developed and iterated various technologies to make us faster and better at identifying this type of material automatically. This includes photo and video matching tools and text-based machine-learning classifiers. Last year, as a result of these investments, we removed more than 19 million pieces of content related to hate organisations last year, over 97% of which we proactively identified and removed before anyone reported it to us."
