Mystery solved, sort of: It seems reasonably clear to me that Daniel Kaufman, a.k.a., Dan Kay, a.k.a. Dan Katze, a.k.a. the Busted Chef, a.k.a. the Montauk Grifter, never actually worked as a producer on Hell's Kitchen, as he repeatedly claimed to the people he conned. But he definitely managed to convince several of the show's former contestants that he worked there, which is some fairly acrobatic grifting.
Yesterday, we brought you the tale of Daniel Kaufman, a.k.a. Dan Kay, a.k.a. Dan Katze, the preternaturally prolific conman who told his victims, among many other things, that he was a world-class chef and a producer on Hell's Kitchen and Chopped—even though he can't cook. Since then, we've learned that he probably did manage to grift his way onto Hell's Kitchen. Also: We've gotten tons of emails from people who have crossed Dan's path, which we've published below.
