Clearly I don't like it if someone says "I'm 95% sure that the guy who bought these five books, is that Dave Singer who attends the W3C".  I'd like to say "not only must my records be anonymized, but re-identification should not occur either".

And setting that rule would also drive re-identification "underground" -- people would still do it, they just wouldn't publish the results, which is *worse*.

The analysis of "public data" would (should?) never get to the stage of identifying individuals.

In your use case, they may come up with "People who buy HTML books are more than likely to be associated with a Web Standards group"

If they did - and could identity - you as an individual, then the original "anonymisation" was flawed, and they are liable to the orginal agreement....
