Joshua created a market to make temporary profit from an N/A exploit to come in #1 for Season 5 Masters. It is likely against the "spirit of the guidelines".

Before people say that it didn't do anything and was "mostly a joke", the league froze at the exact minute that he posted the market, so he was unable to execute on the exploit.

Before people say that no one has the incentivize to actually give Joshua temporary profits, there are people who are already going to be demoted anyways, who have the cash balance, and can make a profit in other markets like /SemioticRivalry/who-will-place-1st-in-masters-s5-le .
