This sounds like you might as well just abandon the plagued site and completely re-build it elsewhere.
That's what I've decided to do, except I'm going to rebuild it in the same place because of some decent backlinks.
In my case my site would not pass a human inspection if I were to file a another re-inclusion request. It's kind of a mash-up site with info available from other places on the web. Nobody misses my site at the moment.
