Daniel Castro of The Information Technology & Innovation Fund recently published a paper supporting the Stop Online Privacy Act (SOPA) currently being debated in congress.

While exploring the structure of national networks through our Mapping Local Internet Control project, we decided to combine our national network data with Google’s AdPlanner data to estimate the overall locality of web site traffic in individual countries.

Ethan Zuckerman wrote up a talk I recently gave on looking at Google’s AdWords as a network of grey surveillance.
Viral Conversations has updated its FAQ to no longer suggest that companies let reviewers keep products and to suggest that reviewers disclose within reviews if they are allowed to keep the products they are reviewing. In a previous post, I pointed out that the site’s policy of encouraging companies to gift reviewed products to reviewers [...]
Peter Li from the Global Internet Freedom Consortium has responded in the comments to my post about snooping by Chinese circumvention tools: We apologize for the confusion here.
