May 31 is the second anniversary of the day when Swedish police raided BT site "Pirate Bay", which was to the surprise of Hollywood that not only did this largest BT site in the world fail to disappear, but also it gained more popularity and traffic. Two years ago, the Swedish police raided "Pirate Bay" and forcibly closed the website. In less than three days, however, "Pirate Bay" opened again. The attention of the media on this event turned out to be a blessing in disguise for "Pirate Bay", as its pirated content and traffic both increased explosively by two times.
