There was a court case against a high school alumni site that sent out "a classmate is searching for you" emails to get people to sign up: http://arstechnica.com/tech-policy/2012/11/how-lawsuit-against-classmates-com-ended-in-paltry-3-93-payouts/ http://arstechnica.com/tech-policy/2012/11/how-lawsuit-again... > The case originated with two lawsuits claiming that Classmates.com had sent out millions of deceptive e-mails telling users that an old friend was trying to contact them, and had viewed their profile or signed their "guestbook." For the great majority, that wasn't true; no one at all had shown an interest in their profile. About 60 million users were contacted, and about 3 million actually took the bait, paying between $10 and $40 to Classmates.
