Well apparently Cutts is talking about manual actions. But if the spam is so blatant and obvious, why didn't the algorithm previously identify it and penalize it, so that there wouldn't need to be a manual review?
Also, why does the algorithm make so many mistakes in which sites it mis-identifies as spam and wrongly demotes. It seems to me that the algorithm is the real problem. Instead of making boring videos, Cutts should start an effort to improve the spam detection parts of the algorithm
