I've been a newbie on a bunch of private trackers, and there's almost always some way to get ratio, you just need to figure out that site's method, and be patient in not-downloading-everything until you can afford it.
For example, like many sites, what.cd generally had freeleeches around the site birthday and the winter holidays: nothing you downloaded counted against you, and whatever you uploaded got added to your account. They also often had artist freeleeches when an artist died; if What was around today, the site would be going wild with Jimmy Buffett traffic. Other sites have bonus points, where you get points for seeding even if no one downloads from you; and then you turn in your points for upload credit. Still other places, you can cross-seed content to get past the newbie ratio restrictions, then move on from there.
It is incredibly frustrating to be new on a site that has a whole bunch of content that you want, but if you're patient or you figure out how the site does things, you can get a lot out of them.
