True but to be fair to webmasters they need to be told if a filter has been applied and given a clue as to how to remedy the situation. Letting webmasters work (hard) on otherwise quality sites while carrying filters/penalties etc is just... cruel. I doubt the article would have been written if he had been notified of why he lost traffic ya know?
(I'm referring to manual penalties, like the one Matt is talking about, not the algo)
