Experts say Facebook’s recent move to ban phony news sites from its advertising network will do little to stop the spread of such articles on its platform. That’s because fake news sites rely heavily on Facebook to steer traffic to their stories to generate ad revenue through other ad services, like Google AdSense. Gautam Hans, a clinical fellow at U-M Law School and an expert on the Communications Decency Act, believes that Facebook has the means to remove more fake stories from news feeds, citing its success in restricting pornographic and violent content. News sources can also be ranked or tagged to help consumers determine their validity, much like Google search results, based on criteria such as user ratings, spam, and traffic so that reliable news sources are more prominent.
