Yeah, I don't care if they cheat at all highscore...But for example, in the game where you have virtual coins or upgrades which can user get only if he played long enough or has spent some money in in-app purchase programmers should care about cheating. Because if user can make unlimited coins the whole purpose of in-app purchase is defeated. And second, I would like to think that my game is not vunerable :) At least not much... — Whirlwind 3 mins ago
