The people who advertised babies and vital organs for sale on eBay are be tracked down and prosecuted. Federal authorities in the US are already investigating the macabre auction of kidneys and babies, although as yet no one has been arrested. As well as investigating those people who placed the ads, the authorities are also chasing those people who made bids. "We have zero tolerance on this," said Michael van Swaaij, European VP of eBay, talking to The Register today. "Some people might think this is just a prank but we're taking it very seriously. That's why we've brought it to the attention of the authorities. "We need to find out who is responsible and prosecute them," he said. "It might seem funny to some people, but this is not funny at all." Although it's widely believed that the sales were just pranks, eBay and the federal authorities are worried some people -- sellers or bidders -- may have been serious. ®
