NEW YORK (CBS/AP) Google is being asked to reveal a user's identity... yet again.
This time the head of New York City's transit union, John Samuelson, wants the Internet giant to unmask an anonymous critic who's been blasting him in a blog.
Samuelsen says in court papers filed Friday that the blog has repeatedly defamed him with false accusations of incompetence and financial improprieties.
There was no immediate answer to an e-mail sent to an address posted on the blog. It's housed by Google's Blogspot.com.
Google Inc. declined to comment. The Mountain View, Calif.-based company says it doesn't discuss individual cases to protect users' privacy.
A number of similar court requests have cropped up since Vogue cover model Liskula Cohen got an online detractor's name by court order last year. In October, a court ruled that Google must disclose the identity of posted damaging material about a woman named Carla Franklin, a former model and actress turned businesswoman.
