If anyone who attempts to distribute such a list is DoSed to oblivion,
people will stop being willing to distribute such a list. Yes, spam is an
economic activity, but spammers may engage in long-term planning. You can't
keep the list of distributors secret. I'd be very interested in techiques
that overcome this problem. I've been looking into tricking existing
widely-deployed infrastructures into acting a distributors, but this raises
both ethical and technical questions.
