In a sense it's the perfect advertising (by both being 'free' and 'covert'), supporting the perfect industry, perfect only in the sense of a feedback mechanism ostensibly designed to stamp it out, only ends up perpetuating its profitability, by squeezing the product between its free advertising and its illegality, inflating prices and profits.
