Well, if it's because it's designed to transfer files, then you'd better kill FTP, HTTP, and all other protocols for transfering files. In case you didn't know, before bittorrent, that's what pirates used. Before the internet they used others that you've probably never even heard of. The violators of copyrights will tend to use the most efficient methods of transfering the files. Heck, at one time that was sneakernet. (AKA putting it on a disk or tape, and having someone run it over to the recipient, often literally.)
