For anyone who is interested I mentioned in August that there are at least two data sets. The second one pops up every few weeks for a couple days then disappears. It's here right now and it appears sporadically when searching.
It's changed dramatically from what I have seen in the past. It's completely full of spam when usually the results are high quality from my perspective.
I'm not sure what's going on but in my opinion something is brewing.
