Our Vandal
I've already humored him and posted external links for all of the Nobel and Pulitzer winners on the talk page, and he's still vandalized the page twice since.  This guy is beyond redemption and IMO is somewhat disturbed emotionally.  The fact is that no other alumni page verifies every single entry, nor should we have to.  I might add this guy has no apparent problem with Nobel sections on other university alumni pages.  If this guy has a question about someone, he can bring it up for discussion on the talk page.  Nobody should have to waste time jumping through hoops to satisfy the needs of a known and repeated vandal.  Besides, it's not the validity or the verifiability of these people that's driving this guy.  It's their very existenceand the lack of similar people at you know wherethat is motivating him, and as such no amount of pandering is going to satisfy him.
