You don't need seebox / ratios, trackers don't know how much you really uploaded, as a matter of fact it's your client that send that information, so you can send anything you want.
This is terrible advice. Any tracker worth participating on is monitoring ratio cheating like a hawk.
I think trackers eventually can find out that bad actors and bad them out. If you claimed to have sent 100 kb but nobody reported to have received them then you are flagged.
In 2008, sure. Any worthwhile monkeying of seeding statistics in a largely compliant user base will obviously stick out like a sore thumb.
