PRISM: an idea for fighting back
Create a web service that provides 1px tracking gifs that webmasters can voluntarily embed in their pages.
Said service has a community maintained list of ip blocks belonging to pro-surveillance organisations e.g. congress, intelligence orgs, military, contractors, general gov, etc.
Any time the tracking image is requested by someone with a matching ip, automatically publish details of that request (referring page, ip, time, etc) to a public repository.
If we can't have privacy, I don't see why they should.
