Being an animal rights supporter all of my life, I have been horrified on multiple occasions when facebook has refused to remove photos featuring animals being brutally injured and even killed. Many of us reported an animal abuser a few months ago (who's name will remain anonymous) and simply received messaged back from facebook saying that they have chosen not to act. Obviously, this needs to be sorted out as Facebook even has a specific section for media showing "cruelty to animals" when it comes to reporting.
