No way to know that or any information that could be said to indicate that the above is indeed the the case. It is conjecture with nothing factual to back it up beyond your belief they have changed that part of the algo. I have seen nothing that indicates this is true beyond, if ... you use placeholders with no content then yes... that is often found by G and many of the directories that got wacked a while back were doing that. There have also been a few papers out of Stanford on this kind of content spam. They may have been a part of any changes to the algo but... that is conjecture and hard to show that it is actually in play. Not disagreeing Peter just saying that it is a possibility that hasn't IMO, been confirmed beyong the wacking of some directories that had other issues that cloud the results and one's ability to be sure that was the cause.
