I would have sent a letter back asking them to prove the file listed was actually their movie, not a video of you expressing your review of the said movie, that you had tittled with the same name, and to prove that they had downloaded it only from you, and was not mostly downloaded from somewhere else.

Once they had done that I would have then told em "dont lknow what your talking about", the IP address they quoted is actually a 24 port router, that you onsell your internet bandwidth from.

Then again it is easy to spout when it is not you facing the bums eh?
