What's training and all that RLHF stuff?
In any case, these companies are well aware that agents are cheating, and don't need user feedback to discover that or realize that people don't like it. I weakly assume that they are trying to get the models not to cheat on assigned tasks, but this "reward hacking" pretty much goes with the territory of RL - not much you can do about it other than try to design non-hackable rewards.
