CEP Senior Advisor Dr. Hany Farid writes: "During a recent three-month period, the Counter Extremism Project (CEP) conducted a limited study using its own video-matching technology and YouTube’s API to identify the presence on YouTube of a small sample of 229 previously identified ISIS-generated videos. No fewer than 1,348 ISIS videos were uploaded to YouTube in a three-month period, garnering more than 163,000 views: 91 percent of the videos were uploaded more than once. Measuring the efficacy of countering online extremism by the number of take-downs and the time to take-down does not tell the complete story. Setting standards for removal time periods is a good first step, but lawmakers should also consider regulating and potentially fining companies based on highly viewed terrorist material and inaction in removing accounts that repeatedly upload banned content.”
