A "troll hunter" typically refers to someone who actively seeks out and confronts online trolls—individuals who post inflammatory or upsetting comments on social media and forums. These hunters aim to expose the trolls' behavior, discourage their actions, and promote a healthier online environment. In some contexts, "Troll Hunter" is also the title of a popular Norwegian film released in 2010. This mockumentary-style movie follows a group of filmmakers who investigate a secret government program that hunts and studies trolls, mythical creatures from Scandinavian folklore. The film blends horror and comedy, showcasing the unique cultural significance of trolls in Norwegian mythology.
