Asking to be removed from the list sometimes does more harm than good. I know that some web sites mass mail to people with a "click here" email for some kind of special offer. They also usually have a "click here to unsubscribe" button. If you click on either of the links it will confirm your email address as a good one and they sell good lists to other people. The same could happen in a case like this. The majority of the people who want to be removed are people who searched for themselves and were shocked by how much and how easily it was available to them. Once they ask to be taken out they could very easily interpret that to mean that the info is correct and use it for other purposes.
