Think twice before you spam Stanford. The Stanford Daily reports today on one student's crusade to make merchants consider the consequences of sending spam. Joe Wagner, working toward a doctorate in mechanical engineering, has taken several companies to small claims court for cluttering his inbox with illegal spam E-mails. He then offers them a choice: He will drop the suits if the companies agree to cut a check to charity. And it's worked. All but four of his targets have made donations to charity. Now Wagner is getting other students involved in the campaign. "If Stanford students and faculty start suing, the word will get out," he says. "Don't screw with Stanford."
