A Virginia appeals court has ruled that Yelp must reveal seven of its users’ identities.

The owner of Hadeed Carpet Cleaning, located in Alexandria, Va., says seven anonymous users posted critical comments, but that they lied and were not customers.

The court ruled that the Constitution protects free speech, but not defamatory speech.

Business law attorney and trial lawyer Seth Berenzweig said the ruling is a significant one. He said the case will allow companies to go after “business bullies in the cloud.” It means that users cannot anonymously make defamatory remarks and then hide behind the First Amendment.
