Oh it happens every once in a while. Alas googling "mailman captcha" turns up mentions of captchas on every mailing list on the net. ;) I'd be surprised if someone hasn't already done it, but we could probably hack one in if necessary.
Now, this post makes the first result ;) Those susbscriptions should be stopped by the mailman challenge, and to pass it they should use real addresses, so at filterable. It *would* be a problem if they used addresses of subscribed members, as not everybody has SPF. I'm more concerned about mailman way of publishing email addresses, too easy to harvest by bots.
