Then there’s Spike the Vote, a sort of Digg-based pyramid scheme in which members earn one point every time they digg an endorsed story. Once members have enough points, they can submit stories of their own to be dugg by the network.
Recently, Spike the Vote’s owner, known only as Spike, sold the site on eBay. A Digg user named Jim Messenger bought the site and gave it to Digg, which promptly shut it down. But Messenger wasn’t just being altruistic. He bought Spike the Vote because he knew Digg’s followers would put a story about what he had done on Digg’s front page. This, he figured, would attract customers to his search engine optimization business.
