This paper outlines the results of a two-month study in which a series of extremist Islmnist websites – registered, hosted or given datacentre services by Canadian internet companies- were empirically observed. The results of this project are inserted into a framework which explores the issue and wrongful application of the “terrorist signifier to substance or nonstate activities, discerns between the purported use of the internet by extremist Islamist organizations for destructive means and the real use of the internet by such groups, and suggests a number of conclusions based on prior administrative responses to the extremist Islmnist use of the internet.
