Even then in a worst case scenario due to the open platform piracy is a possibility. That’s where some of the peace of mind comes from compared to purchasing of digital goods for a closed system.
Pirates are the librarians of the new age. But I caution you, much media cannot be found as soon as you step of the path of the big releases. So it really isn’t the final solution.
If you can’t find something on piracy trackers you just need better trackers.
That’s not always true. There are a lot of obscure/niche products that just aren’t popular enough for there to be perpetual seeders for all of them. Plenty of things have been lost to the annals of time, unfortunately. It doesn’t help that some companies will still witch-hunt pirates offering their ancient products that the company no longer even offers a way to procure legitimately (cough Nintendo cough).
The defaults picked out by Radarr sometimes fail. Not sure where it’s pulling Seed/Leech figures from but those are never right. The only way to find out it to try downloading a few and then nuke the ones that have least seeders you can connect to.
