Spam is not automated anymore. Automated spam doesn't get through modern countermeasures such as human-detection and bayesian filtering, so it is not worth considering. The spam that you actually see today on most sites is hand-pasted by real human beings (at least the stuff that makes it onto my site is. I'm sure you can still find plenty of phpbb sites that are overrun with the old sort). It's hard to do anything about because they'll simply strip the content of an article that would fit well on your site, and stick a link at the bottom. Or maybe they'll skip the link for the first dozen blog entries until they think they've gained your trust. Real spam (versus the wikispam v1agra stuff that gets automatically swatted down) is tricky. And these people are a lot more motivated than trolls, since they get paid when they get a working link on your site.
