Long story short. I have been doing some browsing after seeing so many gaming sites being taken down from attackers. I heard that Th3J35st3r was going after the people responsible for other reasons on MMORPG.com. Being bored I was reading the blogs through a persons site (Th3J35t3r). Mildly curious what Bit Coin was I hit the Bit Coin link on the site. First thing i noticed was the above mentioned thread.
Reading through most of it. I saw a name turn up linked here. http://forum.bitcoin.org/index.php?topic=16457.msg222470#msg222470. @Anonakomis
That name turns up in his blogs. He even links them as LuLzsec at a point. For instance here http://th3j35t3r.wordpress.com/2011/06/16/quick-n-dirty-just-for-clarification/ I know some say it wasn't LuLzsec, personally I don't know.
http://th3j35t3r.wordpress.com/2011/06/16/quick-n-dirty-just-for-clarification/ Th3J35t3rs blog and his twitter http://twitter.com/th3j35t3r?_escaped_fragment_=/th3j35t3r#!/th3j35t3r. Maybe try contacting him. Hope it helps.
