Franklin didn't elaborate on the relationship but said that her case is similar to other online harassment cases.
"Usually when someone's targeting you and you're not Beyonce or a huge celebrity, it's a jealous friend, it's an ex-husband, it's an ex-girlfriend," she said.
In a case that made headlines last summer, Vogue cover model Liskula Cohen successfully sued Google to uncover the name of an anonymous blogger who wrote the words "skanky," "ho" and "whoring" beneath her online photographs. When Google disclosed the IP address, Cohen learned that the blogger was an acquaintance of hers.
Assuming Franklin is able to identify the person who posted the harmful content about her, she said she hasn't fully decided on her course of action, but knows that she'll file a restraining order.
Cyber harassment has "gotten out of control," she said, adding that she hopes her case makes it easier for others to hold Internet bullies responsible for their harm.
"This is just a new frontier," she said. "The laws must catch up with what a marginal few fringe people are doing."
