While thinking about the most resent problem with moderation here, one issue that has occurred before, did stand out to me and that was the complaint that one party was a moderator and also that moderator type admonitions were interspersed among more personal responses, and that the non "official" party could not block them.
What I am proposing is the idea that people who are filling the office of moderators be given a special moderator account separate from their personal account from which and to which all "official" business should be undertaken. Some people and I suspect more than the average number here have issues with authority figures and that may cause issues to flare up more than the might otherwise.
There are of course details that would need to be worked out, but this might be helpful and I thought I would put it before the forum for consideration.
