CNN recently published a sloppy op-ed that accuses Craig Newmark and the folks at Craigslist of enabling and profiting from child sex trafficking, with much hyperbole and bombast ("Craigslist has made selling children a virtual stop-and-shop for predators"). CNN has now published a rebuttal from Craigslist CEO Jim Buckmaster. It's well worth a read, and sheds some light on the specific steps they've taken to combat this and other forms of illegal activity. Personal disclosure here: I've known Newmark socially for more than 10 years. He's benevolent, conscientious, and kind. Accusing him of being a child sex crime mastermind is so dissonant— it's like saying Santa Claus invented AIDS, or that kittens are serial killers. All open systems are vulnerable to some abuse. I commend the actions Craigslist has taken to remain open, while attacking crime.
