Good idea

Group Captain Mandrake of Across the Atlantic has developed a very good standard response for "scumbag" spammers, which is sent from a junk e-mail account.

Hi, Thanks for the uninvited e-mail. It was about as welcome as junk snail mail. You just joined my scumbag e-mail spammer list. It being a list of businesses I will never knowingly do business with. Congratulations.

Hehe. I gotta get me one of those.
