YouTube, Facebook, and Twitter also provide a platform to extremism – from ISIS-related videos to white nationalism. Even though this content clearly violates these companies’ Terms of Service and Community Guidelines, (too) little is being done to permanently remove it from their platforms.During a six-week period, from March 8 until April 18, 2018, the CEP applied professor Farid’s eGLYPH technology to YouTube. With a database of 256 registered extremist hashes, they found no less than 853 ISIS-related videos, which garnered a total of 99,361 views. 221 or 26% of those videos remained online for more than 2 hours and no less than 84% was uploaded more than once. Or to make it even more concrete: On March 10, 2018, a video titled “Hunt Them O, Monotheist” was uploaded to YouTube, calling for firearm and vehicular attacks in Western Europe. The video was originally uploaded by a Somali ISIS-affiliate on December 25, 2017. On March 10, it was available for 1 day 5 hours and 3 minutes before it was removed – amassing 405 views. The following day, the same video was re-uploaded and stayed online for 1 day 15 hours and 29 minutes – receiving 113 views. The video was then once again re-uploaded and available for 21 hours and 34 minutes, with 226 views. In the following days and weeks, the video was re-uploaded four more times, garnering hundreds of extra views. And this isn’t just an isolated incident, according to professor Farid.
