Facebook's Trending Topics section recently has carried a number of trending stories that were either "indisputably fake" or "profoundly inaccurate," according to a report this week. The news feed six weeks ago ran a false story claiming Fox News had fired anchor Megyn Kelly for being a closet liberal who supported Hillary Clinton. Facebook removed the story, apologized, and promised to do better. It appears that despite that commitment, the Trending Topics section is not yet problem free.
