This pdf-format document titled "Law Enforcement Guide to Requests for Information" is purported to be an internal Blizzard document outlining the company's policy on dealing with requests from law enforcement organizations for information about World of Warcraft players. According to Kotaku this was part of a data dump by the Antisec wing of Anonymous as part of their war with their "white hat" counterparts. The document outlines what data they retain, how long the data are stored, and under what circumstances it can be revealed. While it is not confirmed that this is genuine, it does seem plausible, though the way it is interspersed with WoW-themed cartoons is curious. Thanks nin.
