I don't give my e-mail address to anyone that I don't want to get e-mails from.
I tried to sign the petition, but couldn't because they wanted my e-mail address. They are stupid.
I'm not sure what their requirements are. They ask for an street address, which to me is much more private information that an e-mail address. I think they need that kind of information to confirm the validity of the person signing. I checked out their privacy policy, and it seems to be very straight forward. It says:
BeatKerry2004.com privacy policy is very simple. We never collect personal information for any use unless we first ask you for permission. We never sell any personal information or engage in sending unsolicited e-mails.
I am constantly making up new yahoo or hotmail e-mail addresses to avoid spam.
