The term "Index Of" refers to a directory listing on a web server. These are often unsecured folders where website owners store files. In the mid-2000s, savvy internet users realized that search engines would index these open directories. By searching for a specific string like "Index Of" followed by a show title, users could bypass download gates and torrent trackers to find direct downloads of episodes.

For Lost , this has been a rollercoaster. For years, the show was easily streamable. Then, rights disputes would pull it offline. Fans who wanted guaranteed access to the show turned to digital hoarding.
