An Anomaly in the μTorrent network
It always seemed to me that the simplest way to protect content is to just upload a bunch of garbage with the same file name making it impossible to locate the actual movie, app, etc.  It doesn't seem like it would require a lot of sophistication either.  It could probably be done effectively, even showing a 90-minute repeating trailer for the movie or something similar.  I think a lot of people pirate simply because it's the easiest way to get a movie.  If paying $9.99 becomes the easiest way, then a lot of casual pirates will just buy it.<p>Virus writers seem to like this technique, uploading garbage to usenet.  (50Kb files pretending to be a feature film, etc).  I've always wondered why movie studios didn't do more of that.
