you know Joe...this cat and mouse game (it's actually "cops and robbers" a common antisocial/self-righteous moralist game) will go on indefinitely unless you simply reveal this person so we all know who it is, by email address or something.

We have no obligation to keep anyone anonymous and this would stop the game this anti-social person is playing. If you don't do this I might assume the secondary gain from the game is more reinforcing than stopping it! Also, the possibility of identifying anyone who is anonymously obnoxious stops the game once and for all. So just do it...hg
