Ok. This article is pretty wrong. These names and info have nothing to do with the recent Sony hack, they were contest entries from back in 2001. As Devil says, there really isn't any effort involved besides finding the link (they've been posted online for several years). Pretty much the only relation this has to the recent hacks is that Sony only noticed this as they were trying to evaluate their network as a result of the recent hacks.
This isn't a "warning shot" or anything else. Simply a repository of personal information that someone forgot about at some point, which Sony has now fessed up to and shut off (as it should have 10 years ago)
