Check to make sure your content has not been scraped and posted in it's entirety anywhere else in the google index (search for sentence fragments in quotes). If it hasn't then I would dump the URL and move the content to a new domain (either fresh or bought at auction/recently expired).
To do this, install WMT and deindex your entire site. Check that it's deindexed. Post all of the content on a new site (changing the URL structure is ok, but not necessary in my experience). This is like starting the site from scratch so it won't rank until you run some SEO on it. The point of this is to reuse your content so you don't have to start from scratch. If we are talking about a smaller site with only a few pages then I would just start with fresh content period.
Oh and don't waste your time with all those reconsideration requests. If you do SEO you are playing a game where you don't control the rules. Be ready to move on at the drop of a pin (or penalty in this case).
