I remember back before the internet, there was a funny commercial on tv as a public service to make people aware of the law...in the commercial a package arrives at an igloo and the Eskimo looks puzzled to receive such a package....he takes it inside and opens to find an Ocillating fan and trys it out and says Ooooh when he feels the breeze!
The commercial goes on to tell you that if you get something in the mail you did not order, you may legally consider it a free gift!
Apparently scammers where trying to ship random things to people then demand payment or threaten to ruin your credit if no pay....the commercial was quite effective so the criminals would be throwing there money away if the public was aware of this law.
Evil is not new...just takes on different appearances!
