BBC - Troll Hunters (2016) 720p HDTV x264-C4TV

High-profile beauty vlogger Em Ford was a victim of online abuse and fought back. Now she targets the alarming rise of online abuse in Britain by trying to track down the trolls responsible. With the help of technology journalist David McClelland, Em investigates this very modern menace. She is on a mission to put a face to these anonymous bullies and to confront them with their victims. In its most extreme form, trolling is a criminal offence - one that is being increasingly pursued by the British police - but anonymity remains a major barrier to conviction.
