So are you! Your original point hinges entirely on having many non-centralized posts and counting them as part of the list.
My original original point is that moderating mailing lists is not possible. I have not seen an effective counterargument. Reply-to munging and subscribe-to-post do not add up to effective moderation, and are easily circumvented.
I have seen it happen: someone banned from posting to a mailing list harassing discussion participants anyway. Perhaps he subscribed with a phony e-mail address to collect the list traffic, and then just composed replies as himself to everyone in the debate, but excluding the list robot (which would reject the copy).
"Modern" mailing lists still pass through the Cc: material which makes this possible, even though they set Reply-To, and disallow posts from non-members.
I don't care how you set up your mailing list; you're not going to easily be able to moderate out persistent trolls. You can't use IP block banning easily, because trolls don't contact your server directly; they can go through any number of e-mail service providers. If a troll keeps coming back over and over again, using different gmail addresses, are you going to ban everything from gmail?
But, yes, trolls will be replied to. Because, remember, they are not even going through the mailing list robot. They are just sending mail. Of course the troll's mails can be replied to and go back to that person, and to everyone on the CC list that he or she put in.
Not only that, but the troll can include the list address on the CC: line! A reply to the troll will include quoted material from the troll (typically), and since the person responding is a valid subscriber who is allowed to post, that quoted material gets to the list.
So all the list subscribers end up seeing:

http://www.salon.com/2002/03/01/netochka/ The name Netochka Nezvanova is a pseudonym borrowed from the main character of Fyodor Dostoevski’s first novel; it translates loosely as “nameless nobody.” Her fans, her critics, her customers and her victims alike refer to her as a “being” or an “entity.” The rumors and speculation about her range all over the map. Is she one person with multiple identities? A female New Zealander artist, a male Icelander musician or an Eastern European collective conspiracy? The mystery only propagates her legend.
