"Tracking" is not a boolean. A static site that collects only standard
log file data is quite different from a site that goes out of its way to
collect data on screen resolutions, installed plugins, installed fonts,
what a user selects, what they copy to the clipboard, what they enter in
some search input field without submitting anything, whether the user
uses they keyboard or scrollbars or some touch input interface to scroll
and so on and so forth. One reason being that it is much easier to re-
identify returning visitors the more data you retain about preceding vi-
sits. Clearly the easier it is to re-identify, the more "tracking" is
taking place.
