Jeremy, sorry but you are mistaken. The report -- http://papers.ssrn.com/sol3/papers.cfm?abstract_id=1898390 http://papers.ssrn.com/sol3/papers.cfm?abstract_id=1898390 -- was technically correct. In fact, it's KISSmetrics that's distorting what the report said. Shah writes "Mr. Soltani’s paper speculates that KISSmetrics tracks customers across websites based on his observation of a shared identifier on different customer websites." Soltani's paper and my story about it said nothing of the sort. Both point out that KISSmetrics technology gives a user the same unique ID on different sites, a technological choice that would allow its clients to compare their databases -- independent of KISSmetrics -- and share data about users. I find the recent blog post odd, because on Friday, Shah told me it was accurate and that the techniques were legal.
