two-part question actually.

1) To find the spammers, why don't the authorities just act like they're going to buy the product being offered and then just trace it through the resulting postage and / or paper-trail?

2) If they can't do this because the ads are fraudulent and no actual product is being offered, then why does the spam exist in the first place, if not to sell a product?
