This is one of those great mysteries of Glitch. He disappeared while owing people a lot of poop- literally. He went away right after payment was due for his Lottery named "A crappy lotto". I had totally forgot about the lottery until I went there one day and realized that I had got second prize on that one.
Someone needs to get Robert Stack in here with Unsolved Mysteries! -cues creepy Unsolved Mysteries music-
@Draron- Yeah, I think that he was a high roller, so I don't think that he went MIA because he owed people a little bit of poops. Nobody seems to know if it was for personal reasons or for that reason. He hasn't ever publicly dropped a line anywhere, and I'm not sure of the extent of the conversations he has had with anyone else, as it seems that nobody has come forward with any information.
