[linux-elitists] The un-tracking pixel

[Don Marti]

Here's a new, lower-profile way to help alert users
who are vulnerable to third-party tracking: the
un-tracking pixel.

This lets your site participate without having to
add any JavaScript or visible warnings. It sets a
long "Expires" time to avoid loading the pixel for
every page.

You still need the script if you want to show a
visible warning, but the pixel is a way to help other
sites that do run the script. (Good for WordPress.com
sites where you can't add third-party JS, too.)
