TorrentSpy Shuts Down for US Residents

According to cnet news, TorrentSpy, one of the largest BitTorrent trackers has been shut down in the USA. This is what they say about it themselves:

TorrentSpy's decision to stop accepting U.S. visitors was not compelled by any court. Rather, it arises out of an uncertain legal climate in the United States regarding user privacy and the apparent tension between U.S. and European Union Internet privacy laws.

I'm not so concerned about TorrentSpy shutting down, but at the same time they are under a judge's order to hand over user data from their servers. That should not happen. Hopefully their appeal is approved.
