Classmates.com told Anthony Michaels that former classmates were looking for him. If only he would upgrade to a premium membership, they would put him in touch with his school buddies. So Michaels paid the money. Then he discovered that no one was looking for him. Now he's brought a class-action suit against classmates.com for deceptive advertising.
There's a fine line in advertising between what's legal and what's not. "Puffery," which is defined as making exaggerated claims that the average consumer would never take literally, is legal. Example: "You'll love it!" However, making specific, factually misleading claims is illegal. For instance, you can't claim that a product regrows hair if it doesn't.
Classmates.com seems to be on the illegal side of that line, so I predict they'll end up paying out money in this suit.
