In 2006, Aravosis learned that a number of commercial websites were selling people's private cell phone records, and that the practice was legal. In order to publicize what he considered a problem, Aravosis purchased the call records of former presidential candidate and Supreme Allied Commander of NATO General Wesley Clark for $89.95, and then published the records (with the numbers blacked out) on AMERICAblog, bringing the issue widespread attention. In September 2006, California passed a state law banning the practice of pretexting, or pretending to be someone else, used by the websites, with the bill's sponsor specifically citing the AMERICAblog coverage. Clark became an advocate of cell record privacy bills in Congress. Within months, Congress passed a law restricting these records.
