The idea of a total moderation log comes up from time to time:
https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que.... I think it would be a mistake—it would drain our resources while convincing no one. People who see "every" comment they disagree with "always" at the top, and "every" comment they disagree with "always" flagged and removed, are not looking objectively.
I don't mean to pick on you personally!—these are common feelings, rooted in cognitive biases we all share. But the patterns they claim are not even close to true, so anyone who wants to be convinced by evidence can just look at HN in the first place.
Beyond that, there's plenty of transparency available through HN Search and the moderation record of https://news.ycombinator.com/threads?id=dang. Anyone who looks through the record can find numerous examples of us moderating opposite views in exactly the same way, if they want to. The litigious type of user tends not to want to, and although that group is small in numbers, their capacity to consume moderator time and energy is prodigious. It steals a lot of resources away from other users and from the things we need to be doing to improve the site in general.
By the way, I don't claim there's no moderation bias. How can we know what unconscious biases we may have? I'm just saying that certain stock allegations about it are incorrect and have clear explanations.
