Have you let Nikon know about your problem/issue?

Well, that sounds interesting, but do you have any evidence that this is actually happening? We haven't even seen a "massive" number of D600 bodies with bent/flexing mounts, and yet we are to conclude that flexing mounts are leading to additional debris? Most of these "enthusiasts" (do we denote derision in those quotation marks?) are more than likely using the kit lens, so what does that do to the logic? In truth, none of us know whether these spots are plastic or metallic, but it is always more fun to make assertions without backing them up.

Like the non-plastic D700...

More leaps in logic and conclusions... For all we know, these cameras were fab'ed in overly dusty environments, and somehow that dust is deposited in the corner, then released when parts move during shutter actuation. I wouldn't make that claim, because I don't have the evidence, but we'd all be glad and grateful if equally unproven claims about plastic particles being ground lose by bending lens mounts were not presented as truth.
