I'm sorry you are getting spam. I can assure you that Thom does not sell email addresses. I've passed on your comment to the webmaster to see if he has any suggestions.
"Renaissance Thinking About the Issues of Our Day"
I signed up for Thom's newsletter and for the first time in three years I used my private email address associated with my private website. I have never given that email address out to anyone in three years since opening the website, othetr than to family members. I have never recieved SPAM email on the address I gave to receive Thom's newsletter. Not once, not ever.
Within two days of signing up for Thom's newsletter, my private email address started getting bombarded with SPAM for Cialis and Viagra. If you have ever gotten those email's you know they are impossible to stop. Recently, my private email has started getting ads for pornography.
I am 100% sure that either my email address was sold by RT or Thom's site has sold it for spam purposes.Either way, I am having to close that email address down, and inform everyone of a new address. Needless to say, I'll be dropping my subcription to Thom's newsletter.
