Liskula Cohen, 36, has filed a suit in Manhattan Supreme Court in New York seeking an order that would allow her to sue for defamation the anonymous contributor to a blog calling itself "Skanks in NYC".
According to her court papers, the bloggers have "posted entries, including photographs, captions to the photographs and commentary solely about Liskula Cohen that describe her as a 'skank' and a 'ho'".
A blogger titled "Anonymous" said in one entry: "She's a psychotic, lying, whoring...skank". The blogger added that Cohen "may have been hot 10 years ago" but that "desperation seeps from her soul, if she even has one".
Cohen, a Canadian who has appeared on the front cover of Australian Vogue and worked for Versace and Armani, said her depiction as a "promiscuous woman who is filthy, disgusting, foul and a whore" had damaged her "reputation and desirability for endorsing products".
They were also hurtful and "flatly untrue", she said in her affidavit.
Her court order against the US internet giant and its blogger.com subsidiary came after she was alerted to the blog by modeling clients, she said.
Steven Wagner, her lawyer, admitted that New York courts had generally declined to force websites to reveal the identity of anonymous contributors.
"We think we have a case. This is libelous, it's defamatory and you shouldn't just get away with this," he told the New York Daily News.
Last year, Cohen made the headlines after she was stabbed in the face with a broken glass after getting into an argument with a man at a New York nightclub.
