Doxing (or doxxing) is the practice of revealing personal information about someone online without their consent. The word first emerged in the world of online hackers in the 1990s, where anonymity was deemed sacred. The term is still used to describe the unmasking of anonymous or pseudonymous internet posters. Modern-day doxers aim to reveal information that can move their conflict with their targets from the internet to the real world. The legality of doxing can vary from case to case, and depends on what information is revealed.”]
