The Experian bulk mail plan is highly invasive of privacy. Details and URL's below. I've done a quick read of the Experian plan. It is a bit hard to swallow. Rather than go over the entire plan, I'll just bring out a point or two.
People feel their privacy is being invaded by bulk email that is unsolicited.
Experian has proposed a solution. The ISP will provide sufficient information in this list of people who want privacy to link the email address of ALL users with their credit bureau database records. To not share databases with any competing marketing company. Actively encourage user to participate in receiving email solicitations from Experian. Experian also wishes to highly invade the privacy of as many internet users as possible by collecting exactly who they are as a cross reference in existing databases.
