Anthea,
        The point is that you can search for these addresses or
        delegate the task and decline to subscribe trouble makers. It
        is hard work, but your list will remain orderly. Once a
        trouble maker gets on the list you will not get them off
        easily. They may stay there for ages and foment nastymail to
        you through their private mail to list participants. The
        participants often will not catch on to what is happening. I
        thought of this scenario when you first wrote about your
        nastymail but was reluctant to mention it for fear of leading you
        down the path to paranoia. It is very hard to be certain
        unless the trouble maker writes to the wrong person and they
        contact you. You can't just go suspecting everyone. You have a
        committee of fifteen people let them help screen the
        subscribers. -- Paul.
