it's also Google's assessment that the content is low quality. That won't change with a domain change.
Exactly. Everyone thinks a 301 will solve the problem and it might if Google's approach was simplistic but I've seen evidence to suggest once they flag content if you redirect it you're just redirecting flagged content to avoid webmasters easily escaping penalties. Therefore, if a 301 fixed the problem it's probably other factors that caused the original site to be dinged and not just the content itself. Finding out whether it's a content and internal issues vs. domain and external factors is key to solving this puzzle.
I know someone that got a penalty once for most of his sites and used 301 redirect to bypass it and when Google caught what happened they dumped all his sites out of the index for about 18 months. It was posted in this very forum. Not sure they would do the same in this situation, but I've seen it happen so beware what you attempt to do to escape the EMD update.
Sorry to be slow here but what would you report apart from the drop itself ?
The only way the programmers can make enough corrections to get it right are to get enough examples of how the EMD update went wrong. You need to report via Google WMTs or other official channels to make sure they know you think your site was improperly targeted by their latest update so they can make adjustments or simply give you a hand reinclusion.
Sometimes having a manual review of the problem is the only way to get back in the index because I had several ancient sites none of the Panda updates liked for no obvious reason, except perhaps the bazillion IBLs which could've been tainted but were so massive in volume no human could ever fix the situation. So I requested someone manually take a look. They claimed they didn't know why it was getting dinged, yeah right, and fixed it manually.
