Doxing, an abbreviation of document tracing, is the Internet-based practice of researching and publishing personally identifiable information about an individual. The methods employed in pursuit of this information range from searching publicly available databases and social media websites like Facebook to hacking and social engineering. It is closely related to cyber-vigilantism, hacktivism, and cyber-bullying.
Doxing may be carried out to aid law enforcement, extortion, coercion, harassment, public shaming, and other forms of vigilante justice.
Doxing someone like th3j35t3r, social activists from repressive regimes, or even atheists who live in countries governed by Islamic Law could actually put their lives in danger. A fact that these idiots fail to consider or seem to be concerned about.
