Online defamation suits present a new forum for the application of traditional defamation laws. One particular nuance of these defamation suits is frequently defendants’ identities are initially unknown to the plaintiff. Because of this, courts issue Internet service providers with subpoenas requiring them to divulge the identity of anonymous users to defamation plaintiffs. This article proposes a new test that protects online speakers’ right to anonymous speech. The “Anonymous Public Concern Test” incorporates the history of protection of anonymous speech and addresses the critiques of various pro-plaintiff, pro-defendant, and hybrid tests for online subpoenas employed by courts today.
