On several of our lists, we've had
|subscribers get into huge arguments, get abusive, etc. The list managers
|haven't stepped in appropriately (IMHO) to stop the flamewar, and the
|subscribers then claim that they didn't know what to do. The FAQ contains a
|complaint process so that in case of flamewars, subscribers can find out
|what to do (other that just signing off).

Trying to stop in-progress flamewars from BIG EGOS by words alone is
often an exercise of futility.  This is both a technological and
sociological phenomenon.  The former because email distributed,
processed, and read may not be sequential; and the belief that the person
who gets the last word in has won.
