Personally, when I was new, I had luck with these three methods:
1. Download a couple of Bonus torrents (or 10 if you can) and just squat on them to get some points for ratio
(Be careful not to download one that will no longer be a bonus torrent once you begin to seed; I recommend 4 seeders or less for this)
2. Keep an eye on the new torrents that are popping up, or even the new offers that look likely to be accepted. Then go out and try to dl these same torrents, or even parts of them, from other trackers, like the fansub group itself, animesuki or even pirate bay. Once you've got a few files, jump in the seed pool and seed only; it's a good way to ensure plenty of leechers, as the new ones are usually in demand.
3. If you've got the space to spare, download some HD freeleech torrents from here; You can even get by with only downloading a couple episodes of a 26+ episode epic at first. Pick one that has a good sized leecher pool, and you'll likely get some downloads. at the very least, you won't have hurt your ration in the meantime.
I hope this helps.
These methods got me through most of a year, until I made it to freeleech period, and then went nuts.
It requires a little patience, but it pays off.
And it has the added bonus of not feeling sketchy...
