Just for the hell-of-it, I thought I'd check out this Hispanic site that collects names for the DREAMact Amnesty.

I even thought about joining, using some nasty names just to keep an eye on their newsletter.

Then I noticeed a small tab under a text box. Then I figured it out.
The way they get all the names.
What they do is: when someone joins the site, the site is programed to take all the name from that persons address book.
So all the names they have are not necessarily willing or volunteer participants.
