On one hand, Twitter and Facebook offer terrorists new tools. Yet in many ways, terrorists have only moved onto social media because governments and hackers are taking down the websites that are their online headquarters. The concern among some experts is that the West’s efforts could backfire if social media proves more effective at winning converts than the traditional terrorist websites.
"It's like we have this beehive – and then you go and beat on it and the bees go everywhere," says Aaron Y. Zelin, author of the study and a fellow with the Washington Institute for Near East Policy, in an e-mail interview. "It might be a lot easier to keep an eye on those bees and their activities while they're still in the hive."
Concerns that terrorists might embrace social media have been around for several years, but use of the platform has been limited. While Osama bin Laden was alive, terrorists did use social media to a degree for hate speech, recruitment, and training. Still, most Al Qaeda sympathizers remained tethered to Arabic- and English-language websites, which require a login and password to chat, download literature, and view videos and other material.
