Who has been running this classified ad for more than ten years?

Here's an example, from the latest New York Review of Books: http://www.nybooks.com/classifieds/

A return address for a spy ring?

I think the answer is in the comments: "6/4/08 - Just saw this and googled it, of course. If I had to guess on hedge funds, this sounds like something D.E. Shaw might try for recruitment. They're big on the whole "just be brilliant" bit in order to recruit talent. Additionally, I noticed in their own recruitment posts on CL the respond-to e-mail address is Craig-Gen@career.deshaw.com while that one is gencraig@spsfind.com. Coincidence?"

Blog author's reply: "Aha! At long last, after nearly four years, I believe Jennifer may have finally cracked the mystery. This seems pretty plausible. I only wish her link carried me somewhere that I could thank her. Here's hoping you come back and take a bow, Jennifer. Thank you all for taking part in this bit of distributed intelligence exercise. I loved watching it all unfold. And of course, I'm not discounting the distinct possibility that it will continue to unfold in ways I couldn't have guessed."

Perhaps this is a slightly more sophisticated version of the "Make $10,000 a month working from home" scheme used to recruit mules for money laundering.

CTRL + F "Tue. Nov. 24th 2009" on that page. Apparently someone got into the Gmail account of one of the emails used for that ad and found various references to http://deshaw.com, as well as the various other people mentioning D.E Shaw in the comments.

I guess that's the end of the mystery? Or am I missing something?
