In 2000 the owners and operators of Playgirl.com and scores of other adult sites were charged by the U.S. Federal Trade Commission with illegally billing thousands of consumers for services that were advertised as free, and for billing other consumers who never visited the web sites at all. Nevadan Voice Media Incorporated, which ran several adult sites, was also charged by the commission. Sites often suffer from unauthorized, non-paying surfers who use stolen passwords, which can use month's worth of bandwidth in a day, costing the site operator hundreds or thousands of dollars' worth of additional bandwidth fees, all for traffic that returns no money at all. The 2002 "Paragon Electric Co., Inc. v. Buy This Domain" case ruled that linking domain names to pornographic sites is not per se conclusive of bad-faith registration and use, although it does raise that presumption.
