Yes, moderators have a higher responsibility to be controlled and civil. They have to toe the line, and we expect them to show restraint and class. For instance, a moderator cant:
-Call someone names no matter how much they deserve it
-Call attention to the persistent run and dodge nature of someone's posts
-Mention that a particular person finds refuge in the detailed at the expense of the grand.
-Note that someone may act as if they are the moral arbiter of the post and whines and cries when challenged
-That someone routinely insults, denegrates others yet objects when they get the same treatment.
Nope, a moderator can't do any of those things.
