Members of ISIS have been using social networks like Twitter to recruit new members and spread their propaganda, and many people feel that Twitter should be held accountable for allowing this to happen, so much so that the families of two victims of a terrorist attack in Jordan have sued the company. However, a California judge by the name of William Orrick ruled on Wednesday that Twitter is protected by the Communications Decency Act, and that it’s not liable for any content that’s posted on its service by third parties. Similar lawsuits have been filed against Facebook and Google in the past.
