[JURIST] The Federal Trade Commission [official website] announced Tuesday that it has won a court order [PDF copy] directing six advertising companies to stop sending sexually explicit spam e-mails. Read the original FTC complaint [PDF copy]. The order was handed down January 3 by a federal judge in Las Vegas. The companies had agreed to stop the e-mails even before the issuance of the order, but it nonetheless represents the first enforcement of a new regulation requiring sexually explicit e-mails to carry what is essentially a warning label in their subject line (the "Adult Labeling Rule", 16 CFR Part 316.1). The same law also imposes liability on the operators of Web sites profiting from sexually explicit splam e-mail traffic. Read the FTC press release. AP has more.
