For webmasters affected by a manual action, understanding why a particular penalty is applied, what the consequences are and how to adequately address the issue are key to resolving a potentially critical situation.

Experience shows that manual penalties are infrequently issued, and only for serious offenses. Human errors in the process, while not impossible, are extremely rare. It is reasonable to assume that once a penalty has been triggered, it is not a false positive. As far as Google Webmaster Guidelines go, an actual violation was confirmed.
