Research from Boston’s Northeastern University suggests that shutting down known pirate domains is not an effective method for curbing illegal file sharing. Instead, copyright owners should focus their efforts on blocking a site’s ability to process payments from a credit card company or PayPal or simply by offering legitimate services that are more attractive than pirating copyrighted media.

The researchers monitored thousands of popular copyrighted files spanning multiple services in an effort to find the most effective method to combat piracy. They noted that blocking sites or sending DMCA takedown notices has a very short-term effect and are essentially a drop in the bucket.
