Hello, thank you for your comment.

The aim is not so much public shaming but to galvanise the community to flag the exposed content, or to not upvote it at least.

Part of the reason I imagine it will always work, is that humans seems to have a predisposition to equity. And people have a general distaste for people well rewarded for work judged invaluable.

Thus as long as users are rewarded for posts, curators can play on those emotions to motivate the community to flag invaluable contributions.
