How would the open reputation score mitigate bad-faith actors trying to exploit the system?

For example, I believe HN has a vote-ring detector, but I think there's also a decent amount of manual intervention from the mods. Amazon's reputation system is under constant attack through a variety of means (paying teams of people for fake reviews, going to the length of having real transactions on Amazon between fake-reviewer and the seller buying the review).
