John said he has tried in the past to get Twitter to drop the fake account, but they haven't gotten back to him. He said he has also tried to get a "Verified account", but they haven't responded to his requests. Way to go on "customer service" Twitter... ranks right up there with the overpriced Yahoo Webhosting!
UPDATE: Shortly after I made this post, Twitter removed that second link, of the fake. You now see "Sorry, that page doesn’t exist!" there... didn't know I had that kind of "pull"! ;-)
