On one hand, I agree with that D1, but I think everyone (including you) has the sense to figure out he will do terribly. Reasons?
1. He doesn't speak English.
2. He doesn't have any kind of experience in such things.
3. Take a look at the cup so far. It's unclear for you whether it is a private cup or a public one, even though it's absolutely clear what his intentions were, so he was simply unable to figure out how to make it private.
4. Take a look at the description. I have nothing to add.
It's true the rating is not supposed to show his personality and such, but that just proves how much people hate him.
By the way, I already told MonkeyIsland and posted this on the forum, that the ratings should only be enabled once a player finished that given cup, so then the ratings would actually mean something, you could even make an average after that.
