The aim of this study is to, based on the statements of members of various digital groups as well as users on the forum Flashback who express support for these groups, analyze their own understandings of and motives for supporting groups that post names and images (doxing) of convicted or potential perpetrators on the Internet. Based on interviews and digital fieldwork a discursive analysis has been made with the focus on how power, resistance and justice appear in the material. The analysis shows that the primary purpose of why users choose to be a member, support or otherwise use digital vigilantism and doxing has been to be able to protect themselves or others and to warn of what they consider to be dangerous or untrustworthy individuals who have in some way violated the social order by either committing crimes or behaving in violation of norms. Further the analysis show that users have justified their reasons for supporting these groups in different ways, but above all by the fact that the legal system is not considered sufficient to protect those who are considered to need protection in society and create justice. Doxing can be understood as both resistance and power within different power relations. Doxing functions as a resistance to the legal system; the power. By taking the law into their own hands and handing out their own types of punishment, they thus resist the dominant discourse and legal system.
