Ah, so you <i>are</i> passing some client IDs over the GA after all. An IP address perhaps? You know that&#x27;s a leading question, right?<p>Incidentally, I ran similar experiment with gaug.es few years ago - pulled on their tracking API from our server side. While it worked as expected, these sort of shenanigans are good for only one thing - hiding the fact that you are using 3rd party analytics from your visitors.<p>On a more general note - the thing is that you either care about other people&#x27;s privacy or you don&#x27;t. It&#x27;s not a grayscale, it&#x27;s binary. And if you do, there&#x27;s no place for GA in the picture.
