Ehh, I once got a nasty note from a FTer who chose to use "bilgates remailer," whatever that is, to cover up his actually quite literate tracks. I thought from the loftiness of the sentiment and the elegance of the prose that it may have been one of the most respected members of the board (forgive me if I was wrong, o one whom I accused).
It's just part of life. I'd prefer the stuff to have a real return address on it, though.
