Billy and others, I'll set up the code you sent.
Many thanks on the Spam Bot issues. I created a spam bot trap page listing every governmental official in the Korean government. They now get any SPAM, including the pornography. We spoke with the secretary to the Ambassador of Republic of Korea on the issue, and demanded action. Our next step is to ask all recipients of Korean related SPAM to call the Embassy direct. Our mailing list is over 40,000, so this could cause action. I petitioned Senator Gramm today to criminalize email harvesters through federal legislation, both civil and criminal. This is draconian, but SPAM is getting out of hand. Some courts have ruled under the trespass by chattel theory, and I would like to see it expanded to include use of SPAM Bots in general.
