2016, the appeal was dismissed and the Court ruled the domains be turned over to the Swedish state. The site returned to using its original .org domain in May 2016. In August 2016, the US government shut down KickassTorrents, which resulted in The Pirate Bay becoming once again the most visited BitTorrent website. Website Content The Pirate Bay allows users to search for Magnet links. These are used to reference resources available for download via peer-to-peer networks which, when opened in a BitTorrent client, begin downloading the desired content. (Originally, The Pirate Bay allowed users to download BitTorrent files (torrents), small files that contain metadata necessary to download the data files from other users). The torrents are organised into categories: "Audio", "Video", "Applications", "Games", "Porn", and "Other". Registration requires an email address and is free; registered users may upload their own torrents and comment on torrents. According to a study of newly uploaded files during 2013 by TorrentFreak, 44% of uploads were television shows and movies, porn was in second place with 35% of uploads, and audio made up 9% of uploads. Registration for new users was closed in May 2019 following problems with the uploading of malware torrents. The website features a browse function that enables users to see what is available in broad categories like Audio, Video, and Games, as well as sub-categories like Audio books, High-res Movies, and Comics. Since January 2012, it also features a "Physibles" category for 3D-printable objects. The contents of these categories can be sorted by file name, the number of seeders or leechers, the date posted, etc. Piratbyrån described The Pirate Bay as a long-running project of performance art. Normally, the front page of The Pirate Bay featured a drawing of a pirate ship with the logo of the 1980s anti-copyright infringement campaign, "Home Taping Is Killing Music", on its sails instead of the Jolly Roger symbol usually associated with pirate ships. Technical details Initially, The Pirate Bay's four Linux servers ran a custom web server called Hypercube. An old version is open-source. On 1 June 2005, The Pirate Bay updated its website in an effort to reduce bandwidth usage, which was reported to be at 2 HTTP requests per millisecond on each of the four web servers, as well as to create a more user friendly interface for the front-end of the website. The website now runs Lighttpd and PHP on
