ALL OF THEM ARE NARCISSISTS. Okay? Just a reminder.
As for "Sven Manguard"......he's a notorious Facebooker/patroller, obviously just on WP for personal social entertainment.
He popped up in September 2010 and promptly went gnoming using a bot. And a few days later,
went on vandalism patrol. Because he's obviously the second (third? fourth?) account of an
experienced patroller. He's playing the game.
Oh, and btw, this is in his userpage history:
