Update:
The Chow mods never directly responded to our demands to boot bigfellow/John Melvin Hill from the boards. Instead, they deactivated his account and deleted all of the threads that were highlighted in my original post outing him here.
In the past month, a "new" user, qcfoodi, appeared on the Home Cooking and Montreal boards who sounded suspiciously like John Melvin Hill to a group of us. He claimed to be a new transplant to Montreal (yet had a surprisingly good grasp of the local scene) and lists his real name as "Jack." Uh huh. And his profile (http://www.chow.com/profile/1183031) has a number of other suspicious things (including a photo of a bagpiper) that imply he's trying to pass himself off as a U.K. transplant ("fish and chips," "chicken tikka masala"). He even claims his favorite restaurant is in...wait for...Edinburgh!
This guy is such a freakin' loser. And uncreative!
The mods are on to him again, at least on the Home Cooking boards, where they have AGAIN deleted all his posts (see, for example, here: http://chowhound.chow.com/topics/721543?tag=main_body;topic-721543. There's a reply to a no-longer-existant message from him). Oddly enough, his profile has not been deactivated, and his posts remain on the Quebec boards.
Where will he strike next? This guy needs a new MO. Actually, John Melvin Hill needs to get a life!
