I thought that was strange too. But didn't he post a new board location a day or two before he vanished. I didn't write it down because I thought I would be able to reference back.
In the last msg I saw (not sure which board), he actually announced this was the beginning of the "silence". I have no clue if he is a jokester, hoaxster, prankster, or just an idiot, but I was convinced his communications emanated from a university in the U.A.E.
