I've never heard of Doxing (and I read HN) while "Human Flesh Search" is a commonly understood term amoung young people in China. That said, China effectively has a single, unified internet culture, not the many sub-cultures of the english-language internet.
Human Flesh Search is just "人肉搜索" translated word by word, but literally it just means Manual Search, in contrast with automatic search done by machines.
"人肉搜索" coveres a very wide range of topics from its root http://dzh.mop.com/renrou (much like 4chan). E.g. Given the pic with part of a boob and ask for who the celeb is, or some random pic with a nice dress and ask where to buy it. Or you "人肉" the scammer on some Chinese craigslist sites. So later it envolvs identifcation of corrupt official's expensive watch. Theere's a karma-like system to keep the online community engaged.
I welcome the day when this practice, or something similar, catches on in India. Almost every Indian politician has a criminal record, is a thief who siphons money into tax shelters, and does all of this with impunity. Sadly, this trickles down to all the government employees, cops included. This kind of citizen action will expose the crooks for their wrongs and create accountability. Shame is a powerful motivator for change...
