Scott, are you implying that they could somehow affect the score of their game by abusing the game while the ball is still in the shooter lane? Otherwise, I'm not sure how this would affect anything the operator would care about.
I guess what I'm trying to say is that if someone wants to shake a machine for no reason, they could shake it whether the ball is in the shooter lane or not... even without a game coined up. So, I guess I'm not sure why ignoring the tilts when the ball is in the shooter lane (waiting to be launched) is a bad idea. Especially since TNA has an auto launch so that once the first launch is attempted, it's game on. Ok, I suppose if there's a loose or very sensitive switch that is somehow giving points, then shaking the hell out of it while the ball is still there would potentially give someone a free game... but it would seem like a long tiring adventure not worth going on.
