DerGeist writes "Imagine your life ruined by an organized mob that convicts with scant, unreliable evidence. Fueled only by hearsay and rumors, an invisible horde of your fellow citizens begins bombarding your snailbox, email, phone, work, school and family with threats, insults and general harassment. You are forced to drop out of school and quit your job as a result of constant attacks. You are shunned and ridiculed in public as anywhere you go, you are instantly recognized. Although it may seem to be just a second-rate Hollywood nightmare scenario reminiscent of "The Net," this sort of "organized mob" justice is being dealt out freely in South Korea where net usage is booming. So freely, in fact, that almost 1 in 10 of 13-65 year-olds has felt its sting. Could this trend hit the U.S.? Will policing net behavior eventually become necessary?"
