"Recent advances in technology have underpinned the growth of social media and messaging platforms online. However, that same technology has also enabled terrorist exploitation of the internet, where extremist organizations recruit, radicalize, and direct supporters. Since the July 2017 launch of the Global Internet Forum to Counter Terrorism--an organization led by Facebook, Microsoft, YouTube, and Twitter--there has been tangible progress made by both government and technology companies despite the complexity of the issues involved. At the same time, there is now a greater recognition that there will not be a silver bullet solution or a single solution to stopping terrorist activity online but that innovative public and private partnerships will be needed."
