In a first-of-its-kind prosecution, the convicted operator of a “revenge porn” website was sentenced to nearly 18 years in prison, officials announced Friday. Kevin Christopher Bollaert, 28, of San Diego, was found guilty in February on six counts of extortion and 21 counts of identity theft for running a website that posted nude photos of individuals, as well as identifying information, without their consent, according to Attorney General Kamala Harris. “Sitting behind a computer, committing what is essentially a cowardly and criminal act will not shield predators from the law or jail,” she said in a statement. The site, called Ugotposted.com, was one of many revenge-porn outfits to allow anonymous users to post sexually explicit photographs — sometimes of former lovers — without the consent of the photo subjects. “Today’s sentence makes clear there will be severe consequences for those that profit from the exploitation of victims online,” she said.
