I've noticed the same thing about MPC people. Now, I don't want to make a broad statement and say they're all scamming, because I did it once (not the skimming part, though.)

I needed something through the queue fast, so I bit down and did 10 for an MPC, and I'd like to think that there were 10 useful crits there (I did two a day until I hit 10). But if a story did stink, you're right...I wouldn't bother.

Thanks for the offer, I'm far more likely to take you up on it AFTER I do the re-write. ;o)
