If I "downrate" a translation, how does the system guard against trolling? Isn't there a risk that there are some pathological "toxic graders" out there?
I also think there is a person or people who give negative votes to questions for no apparent reason. This also happens at coursers.com. I give questions a positive vote to help neutralize this when it happens.
I would hope they have a method to catch "toxic graders". If someone does this a lot, they would spike in any kind of counts I would think.
