Anonymous speech can have great First Amendment value. But anonymous speech—and perhaps especially anonymous online speech—can sometimes inflict substantial harm, as is the case, for example, with defamation, threats, and copyright infringement. For this reason, First Amendment protections for anonymous speech are far from absolute.
Under what conditions should courts thus require anonymous online speakers alleged to have engaged in defamatory, threatening, or other unprotected and illegal speech to disclose their identities? Disclosing—or “unmasking”—the identity of an online speaker who seeks to speak anonymously to protect herself from unjust reprisal can undermine important First Amendment values, but unmasking an anonymous online speaker who seeks instead to avoid legal accountability for her unprotected (and illegal) speech does not. To date, courts have struggled with a wide variety of tests that seek to determine the point—I will call this the tipping point—at which they become sufficiently confident that disclosure’s accountability gains justify the unmasking of an anonymous online speaker.
This Essay takes an intradisciplinary approach to this problem by examining parallel disclosure challenges in other First Amendment contexts, exploring how lessons learned in those debates might inform courts’ approaches to identifying the appropriate legal trigger for unmasking anonymous online speakers alleged by private plaintiffs to have engaged in illegal (and unprotected) speech. As we shall see, courts considering other disclosure challenges often screen for any impermissible government motive in seeking disclosure and then balance the disclosure’s informational or other benefits against any deterrent effects on protected speech. Together, these two analyses appropriately recognize that the government often—but not always—has good reason for seeking disclosure and also that different disclosure requirements may vary considerably in their potential chilling effects on protected expression.
This Essay then explores how these analyses might inform the search for an appropriate unmasking standard in the online setting. It suggests that courts confronted with such challenges choose an evidentiary standard that leaves them confident both that the disclosure effort is appropriately motivated by an interest in vindicating the plaintiffs’ private law interests rather than in censoring or targeting vulnerable speakers, and also that such disclosure’s accountability gains outweigh their potential chilling effects. More specifically, this Essay concludes that courts might be more suspicious of disclosure efforts sought by a government official and correspondingly impose a tougher evidentiary standard, or tipping point, on that plaintiff before requiring disclosure of the defendant’s identity. Furthermore, courts might choose the appropriate tipping point based on their assessment of the disclosure’s potential chilling effects, which may turn in great part on the nature of the contested speech—for example, as commercial or noncommercial, or of public or private concern.
