We'll force everyone to record their games from an external recording device. Mwahahaha! But seriously, there isn't anything we can do except rely on trust, but if anyone is found cheating (if there's a way to prove it so) there will be consequences, no one likes a cheater.
Personally I record my games (using my webcam), so if any of my scores are in doubt I got proof, but then if I can get some crazy awesome score once I know I can again. I don't need to cheat, never have, and why do so, afterall you might look awesome to everyone else because of your totally kick ass annihilate everyone else score, but inside you'd always know that you are really a suck ass loser. And I'm totally against anyone who does cheat.
But I sure hope that people aren't going to go around calling each other out on everything every time they think a score isn't possible (I know you aren't, just asking a question for that just in case scenario) just because they can't get that high because it'll ruin the whole point of the contest (this happened one year, I almost walked out because of the bullshit), to have fun.
