From the webpage:
“Warrant canary” is a colloquial term for a regularly published statement that a service provider has not received legal process that it would be prohibited from saying it had received, such as a national security letter. Canarywatch tracks and documents these statements. This site lists warrant canaries we know about, tracks changes or disappearances of canaries, and allows submissions of canaries not listed on the site.
Follow us on Twitter for updates and notifications about canaries on this site.
All of the “warrant canaries” I saw listed were from service providers and other organizations.
I recently saw a “warrant canary” posted by an individual (more on that this week).
The thought did occur to me that if enough individuals had “warrant canaries” on fairly short (monthly?) renewal cycles, it would be possible to track the service of warrants through particular communities.
Comments/suggestions?
