As a quick update, we've implemented some list settings last week to help to keep spam off the list. New subscribers are moderated until we're comfortable with their posts. We rejected the idea of keyword based message filtering since not only is a lot of work to maintain, it's trivial to get around it if you really want to post banned words.
Comments and suggestions are welcome.

I dislike this change - how long are subscribers considered "new"? I believe (and I hope I'm wrong) that with this new rule the nanog maiing list will turn into another fulldisc (list activity greatly reduced) by this change. Before this change I had thought of nanog as the new fulldisc - I guess I will have to find yet ANOTHER mailing list for continued activity. And just for reference - have you guys SEEN the "Linux Kernel Mailing List"? - it gets frequent spam posts and yet is perfectly able to ignore the spam/irrelevant posts and continue on its remit.
