True Story - Australian Police have been unable to recommend a prosecution for the following scam:
A company takes out a newspaper advertisement claiming to sell imported hardcore pornographic videos. As their prices seem reasonable, people place orders and make payments via check.
After several weeks, the company writes back explaining that under the present law they are unable to supply the materials and do not wish to be prosecuted. So they return their customers' money in the form of a company check.
However, due to the name of the company, few people ever bother to present these to their banks. The name of the company: 'The Anal Sex and Fetish Perversion Company'.
