“Spamming is the scourge of electronic mail and newsgroups on the Internet. It can seriously interfere with the operation of public services, to say nothing of the effect it may have on any individual’s e-mail mail system. Spammers are, in effect, taking resources away from users and service suppliers without compensation and without authorization.”–Vint Cerf, ISOC Chairman
