Considerable attention has been paid by researchers to social media platforms, especially the ‘big companies’, and increasingly also messaging applications, and how effectively they moderate extremist and terrorist content on their services. Much less attention has yet been paid to if and how infrastructure and service providers, further down ‘the tech stack’, deal with extremism and terrorism. Content Delivery Networks (CDN) such as Cloudflare play an underestimated role in moderating the presence of extremist and terrorist content online as it is impossible for these websites to operate without DDoS protection. This is evidenced by the takedown of a wide range websites such as The Daily Stormer, 8chan, a variety of Taliban websites and more recently the organised harassment site Kiwifarms following refusal of service by Cloudflare. However, it is unclear whether there is any formal process of content review conducted by the company when it decides to refuse services. This article aims to first provide an analysis of what extremist and terrorist websites make use of Cloudflare’s services as well as other CDNs, and how many of them have been subject to takedown following refusal of service. Following this the article analyses CDNs’ terms of service and how current and upcoming internet regulation applies to these CDNs.

As terrorist, extremist, and hateful content has become widespread on social media, platforms have responded with content moderation – the flagging, review, and enforcement of rules and standards on user-generated content online. This chapter provides an introduction to contemporary content moderation practices, technologies, and contexts and outlines key debates in the field. The chapter explores the changing regulatory context around hate speech and terrorist content online in the EU. This changing context, such as Germany’s NetzDG law and the EU’s 2021 regulation on terrorist content online, is setting new standards and statutory requirements for platforms and websites. While content moderation is a form of self-regulation run by companies themselves, the regulatory context is shifting towards multistakeholder governance. This chapter then maps key stakeholders and technologies in content moderation as they pertain to radicalisation, looking at trusted flaggers, Internet Referral Units, and automated content moderation. After providing an overview of the regulatory context, stakeholders, and technologies in content moderation, the chapter explores normative questions about deplatforming, how transparency hinders research and accountability in content moderation, and explores inconsistencies in the enforcement of content moderation rules, particularly in the case of the far right. By providing an outline of the regulatory context, mapping multistakeholder arrangements in content moderation, and exploring key debates, this chapter provides readers with an introduction to the growing literature on content moderation and countering radicalisation.

We welcome the increased focus amongst policymakers on the role played by content personalisation and other algorithmic recommendation systems on online platforms. Such scrutiny is warranted. Terrorist groups exploit platforms that make use of recommendation algorithms, and there are examples of individuals coming into contact with terrorist and violent extremist content via platforms using content personalisation. However, we are concerned that the current debate is, on a policy level, based on an incomplete understanding of terrorist use of the internet, and that a focus on content personalisation is a distraction from more important steps that should be taken to tackle terrorist use of the internet.

The multistakeholder Global Network Initiative (GNI) reviewed more than twenty recent governmental initiatives that claim to address various forms of online harm related to user-generated content — a practice we refer to broadly as “content regulation.” We focused on proposals that could shift existing responsibilities and incentives related to user-generated content. Our analysis illustrates the ways that good governance and human rights principles provide time-tested guidance for
how laws, regulations, and policy actions can be most appropriately and effectively designed and carried out. Because content regulation is primarily focused on and likely to impact digital communication and content, we use international human rights principles related to freedom of expression and privacy as our primary lens.
