Yes, a couple of evenings ago, someone hacked Petman's account. No news has reached me on whom, if it was a personal enemy of his or what, but I heard they got his other accounts, Facebook and whatnot, too. Pet has been cleared, his name secured and he's been unbanned and reinstated to mod status.
Most of the forum, however, was deleted. I watched it happen, hanging out in the SB watching forums go bye-bye. I was one of the people who alerted Caleb via PM once I saw him come online. DarkLink01 was able to save some of the old threads by moving them to forums the hacker didn't apparently have access to temporarily, but mostly, everything went bye-bye.
There is a thread about it in the News an Announcements section. Mases was unable to restore most of the forums due to a fatal glitch in his backup files.
As for the Shoutbox, I am unsure what is going on with it at the moment. There is speculation among those of us still able to access it, but I still don't know the whole story, myself.
