Who is Carcharoth?

Most of the current Arbitration Committee has self-identified on Wikipedia, either currently on the official page, or previously on a talk page or another WP official page.

One notable exception: Carcharoth. He was a popular choice for admin and was elected to Arbcomm, although some of the more destructive and hostile elements of admin ranks opposed his Arbcomm election for irrational reasons.

Reading Wikichecker and his contributions reveals that he is likely to be in the UK, and has a consuming obsession with two things: Tolkein (not surprising, as his name "Carcharoth" is that of a monster in a Tolkein book), and chess.

A very nerdy fellow. Since he has probably participated in discussions on Tolkein forums and Usenet groups, a search of Usenet activity for combinations of "Wikipedia", "Carcharoth", "Tolkein" and "chess" keeps leading to a single name: Christopher Kreutzer.
