There are already mobile games with anti-hack/cheat feature that automatically bans you if your app is modded, and you do not want this to happen with SIF. If you want to cheat and not get caught, the best thing you should do is avoid drawing other people's attention to yourself, the opposite of which Hideko is doing. And considering that majority of players are in Japan and they follow a culture of abhorring dishonesty and cheating, this should be alarming because they can pressure KLAB into implementing it if Hideko continues hacking his scores.
