Why would Google consider a well-ranked site to be "webspam"? How can we see a business we have labored over for years as spammy? That's a bitter pill! I'm sure it takes s kind of objectivity that is hard to come by for a site owner.
I believe this Penguin update has produced the most false positives of any Google update to date.
Just because Google is not ranking you highly at the moment, does not necessarily mean your site is of poor quality. There will be updates to Penguin, I'm quite sure of that.
Read the following article, then consider your next moves, but be warned, Google can change the rules at any time.
