If I didn't know any better, I'd say something like, "Damn, 'Neer must be hitting the bottle pretty hard these days". I'd say that if I didn't know that his idea of "it's time to flirt with alcohol poisoning" is "Thursday".
Also, I really doubt the Gawker leak had much to do with anything. This seems like good old-fashioned social engineering. I think the only reason people thought that was because it happened to be what passes for news on the Internet at the time of FAleaks.
The real "issue" is people using shitheaded passwords. If the Gawker leak hadn't happened it's exceedingly likely the security events surrounding FA over the last few months would have played out largely in the same way.
It occurs to me that this guy seems like he is trying to copy-cat the FAleaks perpetrator(s). He's being far less discreet and "professional" about it too. It might be possible, should anyone (Dragoneer, fd_2 losers, whoever) try, to root this guy out and string him up as a scapegoat. Posting online boasting admitting you're "the hacker" is a big mistake, even if it is to a place like Lulz. As I recall there hasn't really been a first-person word one from the FAleaks people.
