Although regulation frameworks of terrorist and harmful content online have been passed by governments in recent years, regulation in practice remains mostly a matter of solo or self-regulation by the tech sector. That is, when companies draft and apply their own rules for moderating user-generated content on their platforms or when they voluntarily comply with standards shared amongst the tech sector (the Global Internet Forum to Counter Terrorism is one example), without such standards being enforced by law. This, coupled with increased public pressure to address the potential harmful impact of certain online content – in particular terrorist material – has led major tech companies to develop their own councils, consortiums, and boards to oversee their content moderation and its impact on freedom of speech online. In this blogpost, we provide an overview of some of the prominent tech sector initiatives in this area.
