I found the story to be interesting (although of course the player’s behavior is pathetic).
The Ratings Game: Meet Mr. Fifty Percent
Catching this cheater depended on seeing the published games.
The method that he employs is very old.
But it is ingenious to use it to gain rating points.
I remember an old brain teaser that I saw about 7 years ago. It goes like this: Tim the robot can always win exactly half his games against two players. How is this possible? 
That sad. I watched a video of a Magician doing something like that. It was obvious to a chess player that was the most probable outcome. (That he was actually forcing GMs to play another GM and not the magician.)
In any event, the magician himself was still a respectable chess player, something around 2100 to 2200.
