Are these sites replicated on other TLDs?
How wide spread is the duplicate content issues?
Is content scraped from other online sources?
What other "small" seo problems might you have with the site?
Any of the sites I've examined post Panda really did deserve the smack down after close inspection. (that's not to say some got hit that didn't deserve it of course, just mean the sites I personally reviewed).
