The problem with your pledge drive is that some naive or altruistic
individual will always provide an answer, and therefore validate his
existence.

However, I agree to try, although insults and sarcastic comments at least
provide a measure of self satisfaction that are absent when he is just
ignored. Besides, his posts dominate the group, and are nearly impossible to
ignore anyway.

Perhaps on my next trip to France I should make a point of looking him up,
so we could have a personal chat.
