The present article contends that terrorist activism on the Internet is determined by the technical configuration and ease of use of the tool. Engagement in Internet activities considered criminal offenses is not only explained by a progression in the level of radicalization of the individual. Rather, the type of barriers to entry which they must overcome plays a decisive role in the decision. The article classifies the various Internet spaces featuring terrorist content under the categories of “hard platforms” and “friendly platforms”. This differentiation will enable us to identify how the barriers to entry to such activism have evolved over the last two decades and how this evolution has been responsible for different levels of terrorist mobilization in cyberspace. The investigation focuses on jihadist terrorism and uses the antiterrorist operations carried out in Spain during the period 2001-2020 as a case study.

Terrorist groups are increasingly using encryption to plan and coordinate terrorist acts, leading to calls for the banning or backdooring of encrypted messaging apps. This would be misguided. It would not remove the ability of terrorist groups to access this technology and may push them to communicate in ways that are more difficult for Western intelligence agencies to monitor. By creating vulnerabilities in online tools used by a very large number of Americans and other users around the world, it would also expose the broader society to increased security risks.

Deplatforming websites—removing infrastructure services they need to operate, such as website hosting—can reduce the spread and reach of extremism and hate online, but when does deplatforming succeed? This report shows that deplatforming can decrease the popularity of extremist websites, especially when done without warning. We present four case studies of English-language, U.S.-based extremist websites that were deplatformed: the Daily Stormer, 8chan/8kun, TheDonald.win/Patriots.win, and Nicholas Fuentes/America First. In all of these cases, the infrastructure service providers considered deplatforming only after highly publicized or violent events, indicating that at the infrastructure level, the bar to deplatforming is high. All of the site administrators in these four cases also elected to take measures to remain online after they were deplatformed. To understand how deplatforming affected these sites, we collected and analyzed publicly available data that measures website-popularity rankings over time.

We learned four important lessons about how deplatforming affects extremist websites:

• It can cause popularity rankings to decrease immediately.
• It may take users a long time to return to the website. Sometimes, the website never regains its previous popularity.
• Unexpected deplatforming makes it take longer for the website to regain its previous popularity levels.
• Replicating deplatformed services such as discussion forums or live-streaming video products on a stand-alone website presents significant challenges, including higher costs and smaller audiences.

Our findings show that fighting extremism online requires not only better content moderation and more transparency from social media companies but also cooperation from infrastructure providers like Cloudflare, GoDaddy, and Google, which have avoided attention and critique.
