I have a Majordomo hack which allows global bans for subscribe and post.
It has a config file that has lines of the form:


where each part is a regular expression. Oh, and there's an invert option.
Bans get processed the same way as other admin bounces. This was about a
half-hour hack and works quite well. Pester me for it and I'll go to the
trouble of making an actual patch out of.

I have another patch that's been on my homepage for a few years that does
secure subscription confirmation (the one that's part of recent Majordomo
is broken). This has worked quite well to fool automated list subscribers
and spammers so I've never actually had to put them on the ban list.
