The document discusses the concept and history of trolling online. It defines trolling as posting controversial or off-topic messages with the intent of provoking an emotional response from others. The behavior predates the internet and was seen as early as Usenet newsgroups in the 1990s. Modern trolling has become more sophisticated with tools that allow anonymity and the ability to widely distribute provocative or hurtful content. This blurs the lines between virtual and real-world impact, demonstrating that trolling is no longer just an online issue but affects society as a whole.
