It's funny how people get worked up over this.
If you don't want info about yourself recorded, there's a number of things to do -- always buy with cash is one of them. However, this actually
creates a HIGHER profile for you.
The better strategy is to make sure there's public records that show you as an average person; nothing to worry about, move along citizen. And if
you have something private to convey, do it in person or send postal mail.
