One additional thought. While I generally think that open moderation is better, there is plenty of precedent for anonymous moderation.

In addition to the original two moderators being anonymous until they revealed their identities later, many a time Randy & Co have completely deleted threads withouts comment. I've even locked some inappropriate threads only to see them gone later (apparently the FT staff thought they were THAT egregious, and in every case I've had a hard time disagreeing). Those threads were just gone. No explanation or even record of closure.

In addition, not every moderator action needs to be disclosed. For instance, there have been a couple of times where I've deleted responses entirely (not edited/deleted text) because they were incredibly hostile and often containing direct attacks and vulgar language about other members. By getting rid of the response immediately and emailing the member, potential large conflicts were avoided.

So I did want to mention a couple of instances of moderation without comment or even record which seem alright, even if I generally prefer open processes.

Best,
Gary
