Well... you might want to have a look at the last few days of this guys' edits.  Not strictly vandalism, in my opinion, but largely disruptive.  It looks like a case of disruption due to dumbness rather than trying.  In particular, I'd call your attention to the incredibly asinine conversation I've had with him regarding Israel Idonije (though the side of in on my page has been reverted as vandalism by a third party) - I feel stupider just having talked to him. It looks to me like most, if not all, of his recent NFL edits should be reversed, but you're the expert!
