Revotron writes "Anonymous hacker group LulzSec has begun to harness the power of the crowd in their latest griefing attempts. After a day of numerous DDoS attacks on a handful of famous MMOs, LulzSec's phone lines lit up with an estimated 20 calls per second. Using a fairly simple phone redirect, they sent all of their incoming calls to various offices, among them the FBI office in Detroit, Blizzard Customer Support, online retailer Magnets.com, and most recently, the corporate offices of HBGary."
