According to this BBC News story,
A man has admitted being involved in a £500,000 fraud in which he used stolen credit card details to buy his own songs on iTunes and Amazon. … They allegedly downloaded the songs 6,000 times in 2008 and 2009. Johnson admitted being responsible for about 2,000… (he) used “compromised credit card details” in order to gain royalties from the sales of the songs he posted on the websites.
It’s a novel form of theft: repeatedly buy something you own the rights to. It’s easier to do in this digital age, and one, I suspect, we will see more of.
