There have been other instances where this type of setup has been referenced before but it would be interesting to hear how the redirect process works and if it is still as effective as it once was.
What's making the 'other sites' strong is that they are on a Google subdomain - nothing really to figure out. To get the most from this parasite you need to prepare to work some javascript tricks (obviously as the subdomain in question is 'script'), whether that be redirecting to other exploited sites (krpano, pannellum etc), or keeping it all in the code shared in your macro.
actually, I would have been more intrigued by how long it lasts at that ranking a few weeks down the road. the thing is that such methods act extremely quickly at first, but then just as quickly fade away.
