The content creator agrees not to make public comments that are detrimental to the reputation of the game
Sounds pretty clear-cut, if you say anything bad about the game regardless of if it's true or not then you're in violation of this contract. That's ridiculous.
They're are actually saying you can't criticize the game. Now, you tell me who is the arbiter of what is and isn't "criticism", because it never says constructive criticism isn't criticism so presumably is also not allowed.
