Terrorist organizations and their supporters make extensive use of the Internet for a variety of purposes, including the recruitment, training and indoctrination of jihad fighters and supporters. The overwhelming majority of the Islamist/jihadist websites are hosted by Internet Service Providers (ISPs) based in the West, many of which are unaware of the content of the Islamist/jihadist sites they are hosting. Experience shows that, once informed, most of the ISPs remove these sites from their servers. Therefore, an effective way to fight the phenomenon is to expose the sites via the media. It would be advisable to establish an organization – governmental or non-governmental – which would maintain a database and publish information about Islamist/jihadist sites on a regular basis, and/or provide such information to ISPs upon their request.
