A California jury convicted a 28-year-old man of 27 felony counts for posting more than 10,000 sexually explicit photos of women online to extort them for hundreds of dollars each, NBC San Diego reported.

Kevin Bollaert was found guilty of 21 identity theft and six extortion counts while an identity-theft count and a conspiracy count ended in a mistrial. He is the first defendant the state has prosecuted for what is colloquially known as "revenge porn" and he faces up to 20 years in prison, CBS News noted.

Bollaert operated a website called ugotposted.com, on which users could anonymously post explicit images. The victims -- mostly women -- who appeared in the photos generally did not know of or consent to the publication, even though the site frequently listed their names, hometowns and links to their social-network profiles, according to authorities.

On another now-defunct website, changemyreputation.com, Bollaert charged those affected up to $350 to have the images removed. Prosecutors claimed the scheme made him tens of thousands of dollars.

The criminal complaint listed more than two dozen victims, and it took a court clerk 20 minutes to read the list of convictions against Bollaert. Women testified the pictures had affected their jobs and their families and caused them stress and embarrassment, the Los Angeles Times said.

"(Bollaert) is an individual who has no moral compass," Deputy Attorney General Tawnya Austin said.

The case against the man had been filed by California's Office of the Attorney General under a law signed by Gov. Jerry Brown in 2013 that prohibits anyone from putting identifiable nude photos online after a breakup.

The judge ordered Bollaert, who is being held on $450,000 bail, to be remanded in custody until his April 3 sentencing. His defense attorney, Emily Rose-Weber, said she hoped he could show a positive and productive lifestyle until then.

"He didn't think he did anything wrong," she said.

Rose-Weber described her client as an aspiring web developer and insisted his business was not illegal, though she said it may have been "immoral" or "sleazy."
