RAND: US social media strategy can weaken ISIS influence on Twitter. “Opponents of the Islamic State in Iraq and Syria are six times greater in number on Twitter than ISIS supporters, but those sympathetic to the group are more active on the social media platform, according to a new RAND Corporation study. Analyzing more than 23 million tweets posted in Arabic over a 10-month period, researchers found that supporters of ISIS produce 50 percent more tweets than opponents on a typical day, although there is evidence that ISIS opponents are increasing their activity.”
