ATT sent me an opt out form as far as the sharing of my information.  I would have thought all of their users got one as well.  Anyway, MCI contacted me some time ago and knew that I was in the Southwest frequent flyer program.  There's not a company out there that doesn't share some information with their partners.  The only way to stay off the list is to drop out.  Drop way, way, out.

This is the information age.  Get used to it or get ready to move to the remote wilderness somewhere in Alaska.
