As reported by TechCrunch, the downvote button is a way for people to provide a signal to Facebook that a comment is inappropriate, uncivil, or misleading.
On pressing the downvote button (as seen in the picture provided by Christina Hudler below), Facebook hides the comments and provides users options with like 'Offensive', 'Misleading', and 'Off Topic'. This enables Facebook to know whether the comment is objectionable, a form of “fake news”, or irrelevant
Facebook said: “We are not testing a dislike button. We are exploring a feature for people to give us feedback about comments on public page posts. This is running for a small set of people in the U.S. only.”
Recently, Facebook’s North American user numbers dipped, but revenues still soared to nearly $13bn.
Meanwhile, Facebook has revealed that it is also set to introduce new face recognition features that will help users find untagged images, prevent th use of other people’s images by strangers and aid those with visual impairments know what is contained within a video or image.
