There was a long discussion of this on Mailman-Developers in March. See
In short, the way to address this is to disable the -subscribe, -join,
-request, -unsubscribe, -leave and perhaps other email addresses (remove
teir aliases so they are undeliverable), and require the users to
subscribe/unsubscribe/confirm/etc. via the web.
