Ah yes, I'm not sure there. I think maybe whoever compiled this collection scrapped it themselves. I'm not aware of TPB themselves making the proper database publicly available yet.

I think someone scrapped it and created that torrent. You might be asking for some sort of distributed automatically up to date database of pirate bay torrents. That would be cool to have, but its not possible with magnet links like that. The magnet link is based on the content of the file(s). If someone were to upload a new torrent, then the contents of the database changes and the hash changes, and the magnet link changes.

Here is the perl code that was used to scrape that data:
