Now, there are a few things that bug me. One, how do you measure such things? There is no real accurate way. Two, why the hell did I give them all that information? They collected all sorts of personal information, plus they have a guaranteed accurate e-mail address to associate with it. Buy a bit more information, associate real names with e-mail addresses, and you have one impressive market demographic. You know exactly who all these people are and what they are like. It disturbs me. At least I used a couple of throwaway e-mail addresses.
Also, there is this handy page that lets you remove your records. Hopefully they actually remove the records (you never know) but it's worth a shot.
