should you identify the syntax that SE uses for legit server-client transactions, there will be no difference between a legitimate transaction and an exploit. If what I'm led to believe is correct, should a player use this exploit on the sly, a few gold pieces here, a few gold pieces there, only a thorough search through the log would reveal that you couldn't possibly have got a gold piece at that time/location.
The dev would be looking for a legitimate, common server command among bajillions. On a player-by-player basis.
This exploit is bad news bears
