What torrent site has the most seeders?

Most of the sites have the same torrents, it's the trackers that have the seeders. Most torrents have multiple trackers and you can add them by yourself. If the same torrent is on some other tracker you can add the tracker to the torrent, by downloading the torrent file or typing it. I recommend a tracker list, you can find them on any torrent site, the one i use has all the trackers on it's preferences on the torrent file, so I can easily copy-paste them as needed.
