Update April 30th, 2009: Karatechop's account has been closed. Read the full story here.
We first received a tip on a mysterious guild that was blowing through Ulduar's hardest achievements one after the other, all in one day, about a day or two ago. Their gear and raid experience stated very well that they were in no position to do any of those achievements, but we sort of shrugged and let it pass by. It was odd that these players were barely in Naxxramas gear, and their first recorded Kel'thuzad kill was only two weeks prior to their explosion of Ulduar achievements, but we initially ignored these reports because surely, nobody could be hacking the game. On top of that, the forum threads submitted to us all had so many posts deleted from them that they were completely incomprehensible. There was nothing solid about any of it.
Tips on it are still flooding our mailboxes today and a bit more information has surfaced, so let's look into it a little, shall we? The guild is The Marvel Family of US-Vek'nilash. The character Karatechop is the one that has attracted the most attention, and you'll see why in just a moment. If you look over his gear, it's not that bad, really. Epic tank gear, a lot of it from Naxxramas, so it's feasible that he could make some progress through Ulduar. It gets weird when you go to his Statistics and/or Achievements panels. Let's go to his statistics first.
