Thanks for the idea about exporting torrent data using the CLI - I'll look into that.

Re: linking, I currently use sym links to avoid duplicating storage across multiple trackers. My main reason for sym links is so I can link across different devices (my understanding is hard links are limited to the same device). Hard link or sym link aside, the problem is for a given torrent, I don't want to delete it from any trackers if it's performing on at least one of them. My thought process is if I'm keeping the content around for even just one of my trackers, I may as well keep cross seeding it, if for no other reason than to earn that sweet bon. The hard part is identifying which torrents are performing poorly across all trackers. If I can get the data into CSV format, then I think I can massage it well enough to tell which (poorly performing) torrents can be safely purged from all trackers.
