The issue of fake news and its impact has become very prominent in recent years. Despite the fact that fake news is not a new phenomenon, technological advances have constructed a fertile environment for the fake news to be spread rapidly. Social media platforms, such as Facebook, Twitter or YouTube, offer ground for generation and distribution of fake news. Consequently, it is important to study the way social media operates, how fake news is produced and spread through social network sites and what is the role users play. In particular, this study examines the methods and tools Greek users implement in order to spot fake news on social media and counter its spread. Moreover, this research contributes to the theory of fake news by addressing the issue of users’ interaction with news and users’ collaboration in the information era. The data presented in this research was collected from the members of the Ellinika Hoaxes Facebook group, an online Greek community where users exchange knowledge and insights and they collaborate to spot fake news and counter its spread.
