What's interesting about the lawsuit is that the Bittorrent indexing site is not accused of actual copyright infringement but of helping such infringements to happen.
This legal argument, in case you wondering, was one of the backstop legal blows that brought down the original version of Kazaa, the grandfather of the file-sharing index sites.
Torrentspy has always argued, from its earliest days, that it is several steps removed from Kazaa in that it merely runs a search engine for BitTorrent files.
On top of this, it also says it obey requests made by rights holders to remove links to copyright files.
Legal beagles for Torrentspy say the case should be dismissed "because it does not provide any evidence of primary infringement," and add that the complaint fails to prove allegations of secondary responsibility.
Lawyers tend to say things like that, of course, so I expect that the case will trundle on until it reaches the courts, who will then made a quantified decision. Which will go to appeal.
By which time the technology behind Bittorrent will be obsolete, so no-one will care, except the lawyers, who will have generated fat fees from all sides concerned.
