There is no proof of him scamming Dzumior, it's what you believe and I'm not telling you to not believe that. However you are not the one to decide who we should pick as a gamemaster or not, that he helped us with the update was partly the reason. We also need to trust the ones we pick as gamemasters and I trust him.
The reason why I closed the previous thread was because there is no need for a discussion, if he makes a mistake he will lose his position but don't judge him before then. Feel free to create another thread if you still want to complain, but I can tell you already that there won't be any official response in it unless you accuse him of abusing his gamemaster. Everything the gamemasters do is logged, so don't bother making up a lie becuase you might hate him.
