What is the url? Without more info, no one can tell if you got banned, dropped, hijacked, or whatever.
Hate to say this, but it sure looks like a ban for keyword stuffing: http://www.google.com/search?q=www.keyworddigest.com http://www.google.com/search?q=site:www.keyworddigest.com While some may find your lists helpful, Google sees it as stuffing. Case in point: http://www.keyworddigest.com/keyword-list-of-hawaii.htm Your links are still there: http://www.google.com/search?q=link:www.keyworddigest.com So you may have a chance. Either don't let the bots in, or write good articles to add to the lists. You should probably break them up quite a bit more, as well. Hope this helps. Good luck.
