**Nobody's that stupid.  I'm really shocked by how much leeway he's been given and how much time has been wasted on him by valuable contributors, considering how many rules he has willfully broken.  He certainly knows enough to edit articles, make and use templates, create categories, vote on VfD and list articles there, etc., etc.  So he can handle the technical structure but is utterly incompetent when it comes to a) communication with others, b) clearly stated policy, and c) adhering to his own stated intentions?  Why not simply block him and his damn sockpuppet at this stage?  So he hasn't blanked a page like the typical anonymous vandal.  But that's obviously not the only way to disrupt and vandalize.
