But while 18 states and the federal government have enacted or are considering legislation to contain junk e-mail, there's been no public outcry, much less legislation, about the USPS change of address database. It would seem that we just don't get as up in arms about physical junk mail as we do about spam. Maybe we're so used to the snail-mail form, that we don't register it. With junk mail, the financial cost is borne by the sender. Spam invades the inner sanctum.
People have their computers in their bedrooms or their offices.
This is definitely a private space. Now, since spam and cookies and the other means of data gathering have been put literally in front of people's faces, they're becoming more aware of the machinery working against them. And the United States Postal Service is certainly part of the machinery that delivers your daily junk mail. Imagine the outcry if every time you changed e-mail addresses, your ISP handed out your new address to anyone who had the old one. That's kind of what the USPS does with your home or work address.
