Hello, 

We have been working on the exercise of reconstructing an identity using the (still private) pageview_hourly dataset (https://wikitech.wikimedia.org/wiki/Analytics/Data/Pageview_hourly)

TL;DR
It is possible (and easy) to do that with the fields the dataset has now, before releasing it publicly we need to further anonymize it. 

More info here:

Thanks, 

Nuria
