I've never had an experience like that on private trackers. Of the three I've used recently, one has no ratio tracking and just a "gentlemen's agreement" that you seed back. One tracks ratio but doesn't care about it, they only care that you seed back for X hours during a two week period or something like that, and the last one does track ratio, but you also get points for just seeding content even if nobody downloads from you, and you can use those points to get upload credit. None require a 1:1 ratio on anything.

I've never had problems keeping a good ratio on any of these sites, I just let them seed from my media server until I decide to delete them. I even use a fairly small upload bandwidth since my service provider only gives me like 10Mbps upload.
