How can you not get this into your head? It's the same as Magnus Carlsen playing me. It's the same as the team of Real Madrid or Barcelona, playing AFC Wimbledon. It's the same as Roger Federer exclusively playing outside of the top 500. It's like Usain Bolt competing against secondary school athletes.
You can tell in all examples that they are superior, but because they never play anyone stronger, you can't tell what their true rating is. The system can automatically give them a rating, because that's a mathematical algorithm, but it denies giving them a rating because their +- deviation is so large.
It's not a punishment, it's just impossible with any certainty to discern where that player lies until they play someone a bit closer to their rating. The rating system is fine at ranking top players. He's the number 1: http://en.lichess.org/@/Elda64 notice he plays blitz and bullet with opponents from 2100 - 2300. He doesn't just play people 1,000 points lower than him all day, so the system is more certain as to his rating.
So if Marta wants to get a more accurate rating, and supposedly has a 2800 rating, he should play this IM to battle it out.
The player is artificially boosting his rating because he is using selection bias to only play people he is 99% certain he will win against. In a real life setting, it does not work like this. You do not choose who you play. As your rating improves, you get tougher opponents more at your level. For example, my rating is about 1700 in real life. When I play a team, I can't "choose" to play against their 800 rated player, it'd be absurd. I have to play an opponent usually around 1500 - 1900.
So in an online setting when you can "choose" your opponent, you can definitely artificially boost your rating.
