Burch and Brown
The first two inhabitants placed under the glare of the spotlight in this blog have quite a history.
Joshua Burch (ebulker) and Christopher J. Brown (dollar) rate a mention in many places, more often than not in relation to the DDoS attack that put Blue Security out of business.
Spotlighting News linked them together in that sorry episode in May 2006. They even make an appearance in the Wikipedia entry on Blue Frog and the duo scored a hit in Slashdot
Obviously these good ol' boys are not new to the DDoSing game.
