A counterterrorism organization formed by some of the biggest U.S. tech companies including Facebook and Microsoft is significantly expanding the types of extremist content shared between firms in a key database, aiming to crack down on material from white supremacists and far-right militias, the group told Reuters. From the report: Until now, the Global Internet Forum to Counter Terrorism’s (GIFCT) database has focused on videos and images from terrorist groups on a United Nations list and so has largely consisted of content from Islamist extremist organizations such as Islamic State, al Qaeda and the Taliban. Over the next few months, the group will add attacker manifestos — often shared by sympathizers after white supremacist violence — and other publications and links flagged by U.N. initiative Tech Against Terrorism. It will use lists from intelligence-sharing group Five Eyes, adding URLs and PDFs from more groups, including the Proud Boys, the Three Percenters and neo-Nazis. The firms, which include Twitter and Alphabet ‘s YouTube, share “hashes,” unique numerical representations of original pieces of content that have been removed from their services. Other platforms use these to identify the same content on their own sites in order to review or remove it.
