I have a warning inside my Adsense account that states the violation is "scraped content" and gives me a short time to resolve it.

However, the site that is highlighted as the purported "scraper" is a large (200+ page) informational content site that I put online in 1998, and have updated periodically since then (though not for a while, admittedly) and for which I wrote every single word myself!

It's listed in Yahoo, Dmoz and other authority sites, has been referenced hundreds of times from mass media, government and educational sites, and has accumulated over 100,000 incoming links (I mention this just to emphasize that this is "quality" not something thrown together for the search engines in a couple of hours).

I have been an Adsense user since 2003 and this is the first time anything like this has happened.

What should I do? I can't find any way of contacting Google within the Adsense system to report the "false positive" yet it looks like if I don't do anything Adsense serving will soon be turned off!

All suggestions and help very welcome...
