I don't even bother with people that post to me privately when the post is a
usenet posting that they are responding to. As far as I am concerned, those
idiots are just arogant itiots with a bit of paranoia and need to be
ignored.
If I posted something on the usenet, I expect replies on the usenet.
I bet the guy is still getting a bunch of spam even tho he's munged his
email addres anyway.
