The latest prominent "WikiEnemy" to emerge: Harlan Ellison. (See the talk page of his article for a big, vitriolic anti-Wikipedia rant allegedly authored by him.)
A year ago he got the article on himself "temporarily" reduced to a stub via complaints to Jimbo pending some sort of behind-the-scenes resolution of whatever it was that he was complaining about. That resolution apparently never came so a couple of months later I restored all the deleted material. Perhaps he's bearing a grudge over that.
