The focus of this paper is on the extremist group Britain First. As such, it does not explore online terrorist activity but rather examines how a group regarded as extremist is subject to online sanctions. The removal of the extremist group Britain First from Facebook in March 2018 successfully disrupted the group’s online activity, leading them to have to start anew on Gab, a different and considerably smaller social media platform. The removal also resulted in the group having to seek new online followers from a much smaller, less diverse recruitment pool. This paper demonstrates the further impact of the group’s platform migration on their online strategy – particularly on their choice of images and the engagement levels generated through them. The paper puts forward a number of key recommendations, most importantly that social-media companies should continue to censor and remove hateful content.
