I’ve gotten a few asks and been seeing some comments on that post, so I should clarify something: XKit is not black magic.

Blog Tracker alerts you when a person changes their URL, but does not (and can not, anyways) tell you what their new URL is. If it hits a “Not Found” page, it shows you an “error” message on the sidebar, or if it notices an abnormality (like zero posts) it says “changed”.

Your privacy is safe. Blog Tracker can not be used to “track you down” if you change your URL for whatever reason.
