The Counter Extremism Project (CEP) reports weekly on the methods used by extremists to exploit the Internet and social media platforms to recruit followers and incite violence. This week, a pro-ISIS account that linked to propaganda appeared on YouTube and an unofficial media group that supports the terror group released a video titled, “The Severity of the Caliphate” on multiple websites. Lastly, instructions for making TATP (triacetone triperoxide) explosives were shared on a white supremacist Telegram channel.
