if you can peddle forward with no sign of tightening, it can only be fucked..(threaded). But then again, you're trying to tighten it by back peddling, which is actual undoing the sprocket. I imagine if your lock ring is loose (becuase you don't realise it has a reverse thread?) you could get the sprocket loose enough for there to be a few spins of the cranks before you experience tighening (but not many). So how much forward spinning are you getting? indefinate?
