if you read their privacy policy it states that they have already sold your info to third-parties. removing your name from their list does not remove your name from the other lists.
not only is my son listed, but every one of his addresses from birth, including his new house and exactly what he paid for it. also the name of his wife, so if you wanted her info, you could get that as well. even though there are some wrong 'facts' such as the value of my own home and my education and the year of my birth, too much is right, including my home address and phone number. any whacko can stalk or harass me now.
my daughter is listed along with every group she's a member of privately and professionally and what the agendas were at those meetings. in order to get off their list you have to give them your email address. another piece they can sell.
