I download some TV shows, but my ratio is very low.

How do I keep my ratio up?

My torrents are seeding, ports are open etc. Just very little action (not none).

1. Download new content with a decent amount of peers .
2. Upload .

Or try to join ratioless tracker, there are usually the seedtime 24-48h. (Examples: BTN, TSH)
This is good, if your upload speed is low.

cross tracker seeding...

Bonus points system (when it's available)

Know what and when to download.

That's not an option, it depends on the tracker, time, your connection speed and swarm's speed.Knowing what and when to download on what.cd for example will barely keep your ratio at 1/1.

always download particular torrent which is also downloading by others there must be someone to accept upload leechers are also very important for uploading
