the first thing I worked on was duplicated content, to beat Panda, but then Matt Cuts said that Panda has nothing to do with duplicated content.
I know - but that doesn't mean something isn't going on that Matt couldn't foresee. For example, he said there was no Sandbox at first, but later discovered a complex interaction in the algorithm that was creating the Sandbox effect.
In this case, I know someone who did a lot of Panda analysis and they regularly found a higher level of scraped content for Pandalyzed sites than for sites that weren't affected. That is just a correlation, of course, and not a proof of cause and effect. But it was enough for me to take a look and then take some DMCA action as well as to rebuild trust and authority for an affected site. And, it did recover.
Again, I can't PROVE anything here - it's only one example and something else might have done the trick. But with any complex system, like Panda, people can't always predict all the effects that will emerge from the complexity. It seems certain that Panda hurt more than Content Farms, that's for sure - whether intended or not.
