SUMMARY<p>We’re sharing a detailed, end-of-year update on our progress against adversarial networks that we found and removed for different policy violations around the world: Coordinated Inauthentic Behavior (CIB), Brigading, and Mass Reporting.<p>We removed four CIB operations — from China, Palestine, Poland, and Belarus. In our November CIB report, we included a deep-dive research assessment into the China-based network and specific threat indicators to facilitate further research into this COVID-19-focused activity across the internet.<p>Last year, we launched a pilot research platform — built with CrowdTangle — where we're sharing data with independent OSINT researchers and scholars who study influence operations. We'll be expanding this archive to more researchers over the next several months.<p>As part of expanding our network disruption efforts to emerging threats, including from authentic groups, we took two separate enforcement actions under two new security policies.<p>Under our Inauthentic Behavior policy against mass reporting, we removed a network in Vietnam for repeatedly and falsely reporting activists and government critics for policy violations to Facebook in an attempt to silence them.<p>Under our Brigading policy, we took down a network linked to the anti-vaccination movement called V_V which targeted medical professionals, journalists and elected officials in Italy and France to harass them across the internet, including on our platform.<p>pdf report: <a href="https://about.fb.com/wp-content/uploads/2021/12/Metas-Adversarial-Threat-Report.pdf" rel="nofollow">https://about.fb.com/wp-content/uploads/2021/12/Metas-Advers...</a>
