Something is now becoming clear, and I think it's time we put away the name "950 Penalty". The first people to notice this were the heaviest hit, and 950 was a descriptive name for those instances.
But thanks to the community here, the many examples shared in our monthly "Google SERP Changes" threads and in the "950 Penalty" threads themelves, we now can see a clearer pattern. The demotion can be by almost any amount, small or large -- or it even might mean removal from the SERP altogether.
It's not exactly an "OOP" and it's not the "End of Results" penalty. From the examples I've seen, it's definitely not an "MSSA Penalty" -- as humorous as that idea is. (Please use Google to find that acronym's definition.)
It's also not just a Local Rank pheomenon, although there are defiitely some similarities. What it seems to be is some kind of "Phrase-Based Reranking" - possibly related (we're still probing here) to the Spam Detection Patent [webmasterworld.com] invented by Googler Anna Lynn Patterson.
So let's continue scrutinzing this new critter - we may not yet have it nailed, but I'm pretty sure we're closer. The discussion continues:
