Of note.. one of the pushers of this proposal has set up this web page:
http://www.hatcheck.org/listlist.html
The List of Black-Hat Lists

"The goal of this list is to enccourage list owners and list administrators
to adopt a list-management system that confirms all subscriptions, and to
encourage site administrators to take an interest in the activities of anyone
running a list server on their system."

and

"How to Get a Mailing List Added to the List"
If there is a mailing list that you were subcribed to without your
permission, try to subscribe the address [log in to unmask] to that list."
