I have a web site with a set of content.  Another web site on the
Internet contains a copy of my content.  Google has penalized every
single page of my web site for this and completely removed this site

filenames remain the same, but all pages have been modified to be

that will invalidate all of my existing inbound links.  It's a nasty

The sites are both spidered pretty much daily and index changes
normally occur in just a couple of days.

I made the differentiating changes several weeks ago.

I dunno.  :)
