Where is the approval for certain types of pages, though? It is generally not in the search engines' best interests to do this.
Well, the most famous example is the NPR feed pages. Google have apparently told Danny that they approved of those ones.
Those specific pages, but not necessarily those types of pages!
I also consider pages that have been reported over and over again for very long periods of time, yet they still remain in the index to be approved. I know this is a leap, but if you assume they know about them, and can't or won't do anything about them, then there's most likely a good reason. Now, I do understand that they have to be careful of throwing out the good with the bad, but some instances of "spam" that I've heard others report over and over again, pretty blatant stuff -- doesn't get removed. Nor does it seem to incur any penalty as shown by the fact that it ranks.
We've had this conversation before. Sometimes it might rank higher if the spam wasn't there. Sometimes it will be deleted or severely demoted in future.
One particular type of this spam is hidden links. Last I checked it worked great to bring link popularity to sites that use them. (I forget offhand the method used to hide them, but one site in particular I know of was reported numerous times by numerous people, and yet it remains.)
I've seen numerous sites penalised for this.
I really believe that Google does not care about some methods if a given page provides relevant and unique content.
...and that given page ranks in the correct position.
