The front ones are OK, though - can anyone figure why? The only explanation that I can think of is that with LSD, my rear brakes aren't engaged fully very often while the front ones are working much harder... But I'm certainly quite concerned; please advise what I should do now....

The pads are gradually cleaning off the rotor, you can see in the lower photo that the corrosion pitting is quite deep on the outside edge from the original corrosion "event", still needs to be worn down more. Have you tried aggressive bedding of the pads, as described by a couple of us earlier in the thread?
