This paper reviews online gender-based violence (OGBV) as existing within a continuum of (on- and offline) violence, emphasising the connections with different extremist ideologies, including the dissemination of terrorist and violent extremist content (TVEC). It aims to prioritise a gender perspective in responding to TVEC so that social media platforms can better intervene in and mitigate misogynistic pathways to radicalisation that can begin (or be reinforced) online. The discussion recognises that the mitigation of OGBV and online pathways to radicalisation requires a whole-of-society and whole-of-government approach. Whilst there are steps that governments and civil society can and should take, such as overseeing and enforcing emerging regulatory frameworks and voluntary commitments, this paper and its recommendations emphasise the role and actions of platforms.
