Regarding the KMS no hacking, I sincerely doubt that there's absolutely 0 hacking however it's much much much rarer than how often you see them in GMS.
The sole reason is you lose everything if you get caught and banned in KMS.
There is no "delete hackers" button, there's a moral conflict between not getting caught or never being able to play again. That doesn't exist in GMS because it's so easy to create a new account.
Then why don't we have it here in GMS as well?
I actually agree with him about it.
I've been reporting hackers for so long before (I am no longer report hackers) and yet, no one of them has ever got banned...
So it's definitely wasted my time.
Unfortunately, it took me a while to learn this lesson... (that reporting hackers is really useless and a waste of time).
