Piracy

Pros: Good selection, direct access to a few scene groups (scene groups upload mostly on private trackers and these are leaked to public ones systematically), a base level of trust that long time uploaders won't upload viruses, fast download speeds.

Cons: most have requirements on keeping your ratio high which is hard to do if you don't have good upload bandwidth, there may also be a requirement to seed torrents for 10 full days (total, not consecutive) if you can't get to a 1.0 ratio on a given torrent. Your account can be deleted for inactivity.

There are some sites with a freeleech tag which means that downloads tagged with that don't harm your ratio but seeding helps your ratio. In the one I use, you still have to seed for the 10 days. In my experience, because I don't have a seedbox or a good up connection, I rarely can successfully seed at all to build ratio so I am somewhat limited in what I can actually download (only torrents larger than 14 GB or a box set) without throwing my ratio in the toilet.

I could pay for a seedbox or a premium membership to fix this.
