I found these two papers – in of all places the presentation which Emil Kirkegaard and John Fuerst are presenting in London this weekend, which they claim is preventing them from responding to the can of worms they have opened by publishing a large, non-anonymized database of OKCupid dating profiles. This seems like it may become an important case in research ethics and data privacy. You may want to look into it. I recommend starting with this post by Oliver Keyes, but Vox, Vice and Thomas Lumley have all picked up the story. At any rate, the culprits cite these two papers that look quite good, and the second is the lead in to a whole special issue on cumulative science from Psychological Methods in 2009.
