Is eBay's stolen password database for sale?

Although it took eBay itself an absolute age to disclose that a serious breach had taken place, and then completely screwed up the process of ensuring users change their passwords, this should come as no real surprise. Happygeeks' Law states: the larger the corporate, the longer it takes to admit anything and the bigger the chance it will handle it badly. What is surprising is that it has taken so long for the stolen database of user credentials to go up for sale on the dark market.
