On Friday, the Virginia Supreme Court handed down its revised decision in Jaynes v. Commonwealth, an appeal of a criminal conviction under Virginia’s anti-spam statute. The defendant, Jeremy Jaynes, was at the time of his arrest one of the most prolific spammers in the world, sending at least 10 million e-mails a day using 16 high-speed data lines, according to prosecutors. He used his e-mails to sell dubious software products, raking in $400,000 to $750,000 per month.

Jaynes argued that Virginia’s anti-spam statute violated the First Amendment. The statute prohibits sending “unsolicited bulk electronic mail” after having intentionally falsified the e-mail header information, i.e., the information indicating the source of the e-mail. That’s a little different than your average spam statute, which typically prohibits only “unsolicited commercial e-mail.” According to the unanimous Virginia Supreme Court (four members of which switched their votes on rehearing), prohibiting non-commercial bulk e-mailers from forging the header information violates the First Amendment right to speak anonymously.
