Torres-Soriano, Manuel Ricardo. "The dynamics of the creation, evolution, and disappearance of terrorist Internet forums." International Journal of Conflict and Violence (IJCV) 7.1 (2013): 164-178.

This paper analyzes the organizational structure of jihadi terrorism by examining the dynamics of major Internet forums from 2008 to 2012. It highlights the origins, functions, and stability of these forums, revealing a hierarchical rather than a horizontal organization, with significant involvement from formal terrorist groups.
