Facebook has identified and banned groups and pages engaged in misleading political behaviour and removed 652 pages, groups, and accounts linked to Russia and Iran, for ‘coordinated inauthentic behaviour’ that included the sharing of political material. Facebook significantly stepped up policing its platform after acknowledging that Russian agents successfully ran political influence operations on its platform aimed at influencing the 2016 US presidential election. Other social media networks have done likewise, and continue to turn up fresh evidence of political disinformation campaigns.
