Any moderation should show who did it. Flagging should show who flagged.

Seems like a simple and transparent way to show how unbiased and well run HN is.

Flagging can be done by any user (above some karma threshold). This is well known and documented in the faq. A log of this would just make for more tiresome meta discussion. Which is also something the guidelines point out.
