How about something that used to happen on GTA online (when it first came out) when you do a simple task such as, serving drinks, petting dogs, going to scenes and leveling up gives you an abnormally amount of XP, avacoins ect, not actually giving you it but the game gives you it so the average amount of XP you get is around 2 if we had a way that would make the app add a few 0's on to that, you would make a very successful mod, so the server would look at what happened authenticate it as have actually come from code already in the app, which would wouldn't flag up and its bulletproof, stealth tech, this could work, I'm not just talking about XP this could be for avacoins when leveling up aswell
