The admins have, in fact, responded to complaints about the difficulty of the Challenger settings for this game. They explained how they tested the game, and that it didn't appear that it would be as difficult as it turned out to be. I think that's a prefectly reasonable explanation for what happened.
We must always bear in mind that Gyathaar, AlanH, and ainwood put in a lot of work to make this entire thing possible, for which they get no compensation. Heck, they don't even get to play the games they are running. If we feel that one of them has made a mistake, well of course we should provide feedback. I'm sure they want to do the best job that they can. But at the same time we have to be understanding that they are only human and that mistakes are inevitable. Those mistakes shouldn't be taken personally.
Mutineer, I'm sorry that you had a bad experience with this game. The same goes to anyone else who tried Challenger difficulty and found themselves in a situation they weren't expecting. But just because the game was, apparently, ruined for you, does not mean it should be ruined for everyone else. And that's exactly what would happen if the admins were to throw out all of the results, as you (and as far as I can see, you alone) apparently want them to do.
