Why is it called doxxing?

Excuse me, could you elaborate on the origins of the term "doxxing"? I'm curious about how it came to be associated with the practice of publicly revealing personal information about someone online. Is it a recent coinage, or does it have a longer history? And what, specifically, led to its adoption as the term for this type of behavior? I'd appreciate any insights you could offer on the etymology and evolution of this term.
