He is charged with obtaining identifying information with the intent to annoy or harass.
Bollaert's attorney, Alexander Landon, did not return a telephone message seeking comment.
The documents say Bollaert charged victims a fee ranging from $249.99 to $350 to remove the images, using emails sent through a second website, changemyreputation.com.
That led to the extortion charges.
Both websites were inactive as of Wednesday.
His activities "turned their public humiliation and betrayal into a commodity with the potential to devastate lives," Attorney General Kamala Harris said in a statement.
Bollaert was being held in jail in lieu of $50,000 bail.
The department says he told investigators during a six-month investigation that he received about $900 each month from online advertising. However, the department said records from his changemyreputation.com PayPal account show that he received tens of thousands of dollars.
Photographs used as revenge porn can be obtained during a consensual relationship, investigators said, or can be stolen or hacked from online accounts.
The practice resulted in a new California law that makes it a misdemeanor to post identifiable nude pictures of someone else online without their permission and with the intent of causing serious emotional distress or humiliation, though that law was not cited in the charges against Bollaert.
