Spamming Botnets: Signatures and characteristics," SIGCOMM'08, Aug.2008.
Cranton said Microsoft will include in its suits those companies that advertise via spam when it can show that those companies assisted or procured the
spamming, as required under the CAN-SPAM Act.
Spamming, by its very nature, is based on deceit and dishonesty, so the chance of catching and prosecuting perpetrators seems fairly slim.
But, despite recent successes, such as California's landmark anti-spam ruling - resulting in a $2m fine for one
spamming firm - and new legislation currently going through Congress, loopholes are still too wide and too numerous.
Nationwide's corporate policy, which includes an opt-in/opt-out commercial e-mail policy; strictly prohibits
spamming. All company commercial e-mails must contain an "ADV:" in its subject line to signal an advertising-related message, followed by a brief description of the e-mail's content, said Herath.
