I see this:
A U.S. Federal law gives you the power to stop any non-governmental organization from sending you further mail. You can download a copy or Form 1500 or ask for a copy to be mailed to you by telephoning a major Post Office in your area. Fill it out (it's very short), attach it to one of their opened letters, and lodge it at any Post Office. The form was originally intended to stop pornographic junk mail, but the Supreme Court of the United States has affirmed your right to stop any mail that you don't want. If the company continues to send you mail or sell your name they risk being prosecuted as criminals. Burnett comments that with this move ``name removal is virtually assured.''
