I suggest we leave the member's moderation_action on None when it's created, and modify the moderation rules to go look for the list's default setting if the member's value is None.
I think this is a bad idea. From the subscriber's perspective, it changes the list's behavior with no action from her, for no good reason that she knows.
The semantics of these variables is, and I think should be, initialization, not fallback.
