Ask HN: BBB complaint against Google leads to delisting?

I recently had a problem with Google Checkout. Checkout erroneously shut down my account and stopped site customers from making payments. I complained directly and also filed a complaint with the BBB. A day later they reinstate my account without acknowledging any problem. Then two days later, "completely unrelated" my site listing is not referring anyone from google search down from the hundreds per day, any day, for the last few months. Coincidence? Here is a screen shot of google analytics, capturing the dramatic fall over three days. http://imgur.com/JDOwN

Is there anything I can do?
