I wrote a batch script that writes to your hosts file a bunch of tracking URLs which are designed to take data from non users in order to enrich the 'social graph' of people who are either logged out or don't have FB accounts. Please ignore all the flask stuff for now; I plan to turn it into a SaaS app that writes to your host files and continually pushes new tracking URLs as I discover them: https://github.com/jtbarker/nofbtracking (btw the irony of me sharing this on a social site for programming is not lost on me).
