The question of whether a state or the federal government can create a narrowly tailored restriction on cyberspace anonymity without violating the First Amendment remains unresolved[...]The Supreme Court has not directly addressed the issue, but it may soon consider the constitutionality of criminalizing certain kinds of cyber-anonymity in light of the unique nature of cyberspace. This comment explores the various forms of anonymity, examines the First Amendment status of anonymity in and outside of cyberspace, analyzes relevant scholarly commentary, and concludes that a narrowly tailored legislative restriction on "true" anonymity in cyberspace would not violate the First Amendment.
