On my blog earlier this year I made a half-joking half-serious post about Google "tampering" with porn SERP's. Valleywag is reporting some of it's adult content sister sites have dropped from Google index
The personal blog of San Francisco's Violet Blue, a sex writer published in the San Francisco Chronicle and Valleywag's sister site, has been removed from the Google index, along with several other adult sites.
Now looking at some of the [site:] searches for the domains they seem to be going through the same "supplemental problems" that many other webmasters are also reporting:
DazzlinDonna/Graywolf, site: used to show purely random pages a year or so ago. Now site: tends to show shorter urls higher instead of a random order. I’m happy to see an example if anyone wants to post an example where a site: search looks strange, but I’ll pre-ask people to step into Googlers’ shoes and realize that supplemental results by themselves don’t indicate badness/penalties/problems.
However it seems like me lots of people actually want their pages to rank for things and not go into supplemental hell with this "non update" no matter what Kool-Aid the googlers are serving us while trying to sell us new footwear.
