Some might be interested in this Facebook dataset release, and the issues I raise regarding its "anonymization".
Facebook Data of 1.2 Million Users from 2005 Released: Limited Exposure, but Very Problematic
Recently, a Facebook dataset was released consisting of the complete set of users from the Facebook networks at 100 American institutions, and all of the in-network “friendship” links between those users as they existed at a single moment of time in September 2005. Surprisingly, it initially included each users unique Facebook ID, meaning the presumed “anonymous” dataset could be easily re-identified, potentially putting the personal information of 1.2 million Facebook users at risk.
