What I didn't know is that apparently some of those "200 address labels for $4.95" outfits are also in the business of selling your name to folks that want to sell stuff to people who have just moved. I found this out only when I got some junk mail addressed to "lara7", which only the address label folks would have known to attach to my new home without also knowing my legal name.
As an experiment, I'm thinking of getting address labels made for the cats or dog to trace the flow of junk mail from there...and then having the cat do an identity theft on the dog.
