[Mailman-Users] Global ban list for all lists?

[texas critter]

Is there any way to globally ban a specific email address from joining any
list on the server?  This is not about banning general spam so I don't want
to block all mail from these addresses, I just want to prohibit them from
ever joining any list on my server.

I'm running Mailman 2.1.3 (cPanel/Linux) and I have root access.  I looked
thru the list archives and the Mailman FAQ, searching on "ban" mainly and
didn't see anything helpful.
