Excerpt:
Tuesday mornings, Monika Bickert and her team of content cops meet to discuss ways to remove hate speech and violent posts from Facebook Inc., the world's largest social network. Recently, the group added a new tool to the mix: "counter speech."
Counter speakers seek to discredit extremist views with posts, images and videos of their own. There's no precise definition, but some people point to a 2014 effort by a German group to organize 100,000 people to bombard neo-Nazi pages on Facebook with "likes" and nice comments.
Facebook Chief Operating Officer Sheryl Sandberg appeared to endorse the idea during a panel at the World Economic Forum in Davos, Switzerland, last month, suggesting a similar "like" attack could hurt groups like Islamic State.
