Not trying to refute you, but how can that be the problem? From the email you cite,

"Please be assured that your Adsense account remains in good standing and any actions taken on this domain do not affect the performance of your other Adsense ads."

The author of the blog post states after receiving that email he took the Adsense ads off. This was also in Feb. 2009 and the account was closed in April 2011.

Does the Adsense team (or whoever) go back and look at incidences from 2+ years in the past when looking for people to ban?
