It would be really easy for me to manufacture 20k USD in charges, receive the MR, spend them, and get refunds from the merchant. They like to wait until a while after the statement has been paid.
Amex could just charge them for the negative MR balance. I doubt your theory because I don't believe there are that many fraudsters do this to become a problem Amex has to address. Fraudsters would probably go after $20k, not 20k MR points.
I'd think someone screwed up in IT.
