Story highlights Kevin Bollaert was convicted of 27 felonies for operating a "revenge porn" website

Users submitted personal information about the subjects of explicit photographs

On another site, he charged people up to $350 to take down photos

(CNN) The owner of a now-offline "revenge porn" website based in California was sentenced Friday to 18 years in prison, the San Diego office of the state's attorney general said.

Kevin Christopher Bollaert, 27, had been found guilty in February of six counts of extortion and 21 counts of identity theft. He faced a maximum of 23 years in prison.

Prosecutors said Bollaert created a website that allowed people to post explicit images of people without their permission. The site also posted personal information of the people in the pictures without their consent, Attorney General Kamala Harris said.

The sexually explicit material, primarily of women, was routinely posted by angry former boyfriends and ex-husbands, authorities said. It contained their real names and links to their Facebook profiles.

Bollaert created a second website that solicited payments of $250 to $350 from people who wanted to have the photographs deleted. Bollaert made about $30,000 on that site, the attorney general's office said.
