Specifically on a full moderation log your links also show how it would be troublesome in some ways I perhaps hadn't thought as deeply about. After all even if you moderate 9999 things right the same crowd is going to want to parade the 1 - now with more details as to why. At the same time I still think the same set of people are going to complain either way and the data isn't really helpful to them as much as the rest of the people anyways. I realize I'm extraordinarily unlikely to budge your views on this due to volume of experience/thought/interaction with this topic you've had but just count me in the selfish "I'd rather the log/actions were public for us average user and then your half a day of emailing was explaining the details to the troublesome bunch rather than with the average user spending time trying to understand".
I'll close with a smaller push of "and even if the site never does a full moderation log, not signaling moderated post/comment actions at any level only feeds that small group on believing everything unpopular they say is being censored 100% of the time instead of x% of the time". With that I'll leave you some peace on the matter :). Thanks for the time and reading through (yet another) user's view on this and for the good moderation of the site as always.
