Karen "Gary" Kazaryan, 27, of Glendale, Calif., may have had as many as 350 victims, KTLA-TV reported. He was sentenced Monday after pleading guilty in July.
Prosecutors in sentencing documents said Kazaryan hacked into online accounts and then searched them to obtain information or pictures that could be used for his online extortion scheme. If women refused to send him new salacious photographs, he posted ones he had found in private accounts to public sites.
He also emailed their friends and asked them to send naked pictures, investigators said.
"He had two goals every time that he accessed these accounts: get more naked pictures in any way he could, and get more victims," prosecutors said in a sentencing memorandum. "His victims were devastated and felt like they had been raped. They continue to be thoroughly traumatized by his criminal conduct."
