Re: Privacy Icon Study

I have concerns that DNT in its current form does not provide a way for sites to signal back that they will respect the user's no tracking signal. Based on my P3P experience, I am also very concerned about incentives for adoption. 

There is some useful information about the DNT proposal at 
https://www.eff.org/deeplinks/2011/02/what-does-track-do-not-track-mean

I'm working on a paper reflecting on 15 years of efforts to develop privacy icons and machine-readable privacy policies... I turned an excerpt of it into my comments to the FTC, which you can find at

If someone violates "Do not track" I may not know for ages, if ever -- the tracking was internal to them and the places they made it available to.  It is a worry, I think -- that doesn't make it useless, however.
