Some moderators have "moderator" as part of their name. I see a difference between posting in a forum under the name moderator versus posting as a regular username who happens to be a moderator. More than one moderator I know posts as a number these days. Others appear to have acquired a name that includes "moderator" to make their moderator posts. It isn't about being dishonest in most instances, it is trying to not set themselves apart when contributing to a forum or giving their opinion.
Anyway, that is my two cents. Now, I would ask that you please don't continue on and relate it back to one moderator you have had issues with. That has been beaten to death to the point of absurdity, and you have too much positive to contribute anyway.
