If the person replying does a reply-all and doesn't remove the lists of
which she is not a member from the recipients.

Attempting to train your list members is futile. What you can do is
set Privacy options... -> Recipient filters -> max_num_recipients to 2.
This will cause any post with 2 or more direct (To: and Cc:) recipients
to be held and then you can reject those posts. Whether this is more or
less burdensome than rejecting the non-member replies from the
cross-posted lists is something only you can decide.
Also this creates another problem. If, as we strongly recommend, your
list doesn't munge Reply-To:, and your user's MUAs don't offer a
reply-list option, they probably want to reply-all to list posts which
will cause their replies to be held too.
Bottom line: I feel your pain, but I don't have a satisfactory solution.
 My experience with lists whose members are not email wonks is that
attempts to alter member's behavior only result in their thinking you're
a jerk and don't modify their behavior.
