Canadian model Liskula Cohen is used to the sometimes catty attitudes of the New York fashion world, but when one woman decided to dig her claws into her in an online blog, Cohen fought back.

In August 2008, Cohen ran across a blog on Blogger.com, called "Skanks in NYC." The now defunct blog included five anonymous postings that read "I would have to say the first-place award for 'Skankiest in NYC' would have to go to Liskula Gentile Cohen."

The posts included pictures of 5-foot-10 blond Cohen and an unidentified man in sexually suggestive positions, with captions describing her as a "skanky ho'" and "a psychotic, lying, whoring skank."

Cohen, 37, a Canadian-born cover girl who has appeared in Vogue and other fashion magazines, was livid and demanded that Google, the owner of the blogging service, give her the poster's identity. When Google refused, Cohen took it to court -- and won.

On Tuesday, New York Supreme Court Judge Joan Madden agreed that Cohen was entitled to information about the blogger and ordered Google to turn it over.

"It was very fair and I am very happy with the verdict," Cohen told CTV News Channel Wednesday night

In her ruling, Madden cited a Virginia court decision in a similar case that found that online bullies should be held accountable when they cause injury.

"The protection of the right to communicate anonymously must be balanced against the need to assure that those persons who choose to abuse the opportunities presented by this medium can be made to answer for such transgressions," the judge said, quoting the Virginia decision.

Google complied with the ruling Tuesday evening, submitting the creator's IP address and e-mail address -- all that is required to register for a blog on Blogger.com.

Cohen told ABC's "Good Morning America" Wednesday that she immediately recognized the blogger, describing her as an acquaintance who was a regular fixture at dinners and parties. Cohen has not revealed the blogger's name publicly.

Cohen and her lawyer, Steven Wagner, said they are now planning a defamation suit against the blogger. Cohen alleges the blog has been harmful to her career and that prospective clients would question her about the blog and what she was doing in the photos.

While Wagner said he was happy the court recognized that "the Internet is not a place where people can freely defame people," the attorney for the blogger disputed the judge's reasoning.

Anne Salisbury said her client's rant was not unusual for the Internet, and that online name-calling is so rampant "in comments sections, on Twitter, on blogs" as to practically be part of the web's essence. She warned that Monday's ruling has "potentially damaging implications for free speech on the Internet."

CTV's legal analyst Steven Skurka says Tuesday's court decision against Google does not mean that Cohen will be successful in her defamation suit against the blogger.

"This woman has not won her lawsuit; she's far from that. She's going to have to show that harm was caused to her," he told CTV News Channel.

"The problem with a lawsuit such as this is that you repeat the... malicious gossip. And who wants in the public domain aired the fact that you're being called a 'skank' and 'a psychotic whore.' Good for Ms. Cohen for doing it but I don't think many people would want to do that in her position."

Salisbury contends her client's blog would have remained in obscurity had Cohen not filed her lawsuit. The site had negligible traffic and only five posts, all written on a single day.

Skurka says there might be truth to that. He notes there has been no evidence that prospective employers who heard about the blog then refused to hire her.

"It doesn't mean that she didn't get the jobs anyway and it doesn't mean that they found it credible. So the mere fact that they were aware of it caused [Cohen] discomfort. Does that lead to a successful lawsuit? I would say no," said Skurka.

After the ruling, a Google spokesman expressed sympathy for "cyberbullying" victims but said the company only divulged the user information because it was ordered to do so by a court.

"We sympathize with anyone who may be the victim of cyberbullying. We also take great care to respect privacy concerns and will only provide information about a user in response to a subpoena or other court order," Google's Andrew Pederson said.
