I stand corrected then. I quickly checked the FAQ and it only mentioned playing one account against the other. But you make a fair point nonetheless: even if the rules allowed it, it would be massively unfair.
I don't get why anyone would need a second account anyway: If I want to play a game that does not affect my ranking, there's "friendly mode" for that.
