I don't think it is that simple. I bet that you click-accept something like "By ordering this file, you state that you have the necessary permissions and you clear our asses of any responsibility" when ordering a file. And even if you don't, it's still you who ordered the torrent download (resulting in re-distribution to other clients), which (I believe) matters more than the fact that you're not the owner of the client box.

You didn't order Boxopus to upload anything back to other torrent users and they are the ones who have chosen to send you the data they received. Seems pretty obvious that they are participating in infringement regardless of what their ToS say. I hope they have some good lawyers on hand.
