Annual assessment maps out the challenges faced by government and tech platforms in countering terrorism online, and highlights concerns about forthcoming Online Safety Bill.

Tech Against Terrorism today welcomed the latest report by the UK’s Independent Reviewer of Terrorism Legislation, Jonathan Hall KC. This year’s evaluation focuses on the internet, which is described as the ‘new frontier for counter-terrorism’.

The Independent Reviewer’s report gives an excellent assessment of the complexities faced by both the UK government and tech companies when dealing with online terrorism.

The report articulates the challenge well by stating that: ‘Total outsourcing of counter-terrorism to private companies could lead to a loss of trust in civil society and in government, alongside with legitimate fears that tech companies are ill-equipped to make decisions touching on terrorism and national security.’

The report therefore recognises the role of partnerships between public and private sectors in countering terrorism online. Since its inception, Tech Against Terrorism has pioneered public-private partnerships and the Independent Reviewer’s report explains the organisation’s work particularly with smaller tech platforms.

The report discusses Tech Against Terrorism’s ‘impressive focus on transparency and detailed analysis, going beyond mere research, which attempts to identify, through inclusion in a Terrorist Content Analytics Platform, content whose removal is justified.’

Tech Against Terrorism’s Terrorist Content Analytics Platform aims to track, verify and alert platforms of terrorist content online. Since its launch, the platform has identified over 43,000 pieces of terrorist content and alerted over 100 platforms.

Tech Against Terrorism has also placed a priority on identifying and removing terrorist-operated websites and we are grateful for the report shining a light on this rising pernicious threat.

The report raises unresolved concerns about the Online Safety Bill, which is currently going through the House of Lords. While the Bill rightly places a particular emphasis on protecting children, Jonathan Hall K.C. questions ‘why the Online Safety Bill excludes terrorism content from heightened child-specific duties.’

The Online Safety Bill must still navigate the complexities of content moderation especially in relation to what the report describes as ‘terrorist conduct’ and ‘terrorist content’.  According to Jonathan Hall, how to define ‘terrorist content’ is left wide open by Online Safety Bill, as is the question of whether certain forms of ‘terrorist content’ are more likely to lead to violence than others.

Amongst the proposed recommendations for the Online Safety Bill, Tech Against Terrorism called for clearer definitions for harmful and terrorist content, as well as appropriate support mechanisms to ease compliance of the Bill.

Overall, commending the Independent Reviewer’s report, Adam Hadley, founding Executive Director of Tech Against Terrorism said: “The latest report from the Independent Reviewer of Terrorism Legislation provides an essential basis for developing more robust legislation against online terrorism in the UK. Sounder legislation will give a clear direction for tech companies to act on terrorist content found on their platforms. That is why we agree with Jonathan Hall’s overarching call that the aim of content removal in the name of counter-terrorism must be to reduce terrorist violence not merely terrorist offending.”
