I think that changing the rank system is the most effective way, though. Right now, the ranking system actually favors spamming and low-quality posts! A person who spends little time on each post will make many more posts than a quality poster who puts time into each post. So changing it from a system that favors spamming to one that favors high-quality posting is the way to go, because they'll have no motivation to spam.
