One of the greatest challenges in combating internet piracy is the race to the bottom. Web sites that traffic primarily in pirated works or warez frequently relocate to jurisdictions that have weak or no copyright enforcement, either due to defects in the laws themselves, or because they do not require internet service providers to act as partners in shutting down illegal activity once that activity has been identified.  

One such safe haven has just been shut down.  Denmark’s highest court has required an ISP to deny access to The Pirate Bay.  As Geek.com points out, The Pirate Bay has been viewed as a significant thorn in the side of the MPAA's enforcement efforts. Prior to this decision, the Pirate Bay benefitted from Danish copyright law, which was lax by western standards.
