If the Federal Trade Commission won't, Joe Wagner will. Fight spam, that is, even if it originates from legitimate companies likes Kraft and Bob Vila. A Wired piece profiles the 37-year-old mechanical engineer's efforts, through lawsuits, to bring to justice spammers who violate the CAN-SPAM Act. "Wagner is a kind of private-sector, internet version of New York State Attorney General Eliot Spitzer," writes Adam Penenberg about Wagner, who donates all money he gets from suing spammers to charity and nonprofits (so far, about $70,000 in judgments, settlements or "directed donations").
