Tech platforms have been through several regulatory phases concerning the countering of terrorist content on their platforms: from a lack of regulation, to the government demands of self-regulation, to the present day where regulation has been implemented across the world. Much of this regulation, however, has been heavily criticised. After consideration of these criticisms, and research into regulatory approaches in a range of other industries, this article proposes a responsive regulatory approach to countering online terrorist content. Responsive regulation argues that regulation should be responsive to specific industry structure because different structures are conducive to different degrees and forms of regulation. This article categorizes tech platforms based on different compliance issues: awareness and expertise; capacity; and willingness. It then proposes four regulatory tracks in response, in order to try to mitigate the occurrence of these compliance issues.
