"U.S. Revamps Line of Attack in Social-Media Fight Against Islamic State," The Wall Street Journal

Recent initiatives by technology companies to push back against Islamic State's social-media messaging highlight a sobering fact: The U.S. government's battle on that front has mostly sputtered. Since early 2014, approximately 100 individuals have been arrested in the US on charges related to providing support to the Islamic State. In 69% of the cases, officials found the individuals had watched or read the group's electronic dispatches, according to the Center on National Security's report, Case by Case: ISIS Prosecutions in the United States. The government's countermessaging efforts so far have been scattershot and, some close to the government think, largely ineffective.
