A prankster? Since when are pirates people who will only put things up for free? Strange distinction here...
One thing that might become funny in the short future is how Amazon might find itself in even worst a situation than that of some torrent sites. Torrent sites have always argued that they cannot be deemed guilty of pirating because they do not host the files and have no responsability over the content of the files shared. Well, Amazon hosts the files and should supervise content! I say they should go on trial in Sweden!
