For cases to be rare doesn’t imply it’s not a vulnerability on fairness for the users. It’s very easy to take advantages of human mistakes in the current stage. Even I could do it: Suspicious activity: change to pending + challenge by a user on this forum
It doesn’t matter that we can’t solve it at the moment. Addressing the issue is important and looking for better options. I get that the gas costs are a problem but I’m sure there are alternatives to the flow.
My point is, let’s keep thinking about it and not shut it down just because it’s rare. Maybe the solution isn’t even this and more about Kleros decision making.
EDIT: The bigger this project gets there are more chances these edge cases occur, I can easily picture people “hunting” mistakes just to get a piece of the stake and not for curation as it’s actually profittable.
