A "expert" (no one really knows just what the expertise relates to) suffering from a self-induced delusional paranoia who thinks that any internet forum or BBS that is not open to the public is filled with hackers and evil, baby-eating Satanists that are plotting to take over the world. That is, after they kill him first, of course.
