I recently used Google Drive to share a file with
Anyone with the link ("Anyone who has the link can access. No sign-in required."), but did not yet distribute the link to anyone. Thus, I cannot imagine how anyone might be accessing this file yet.
When I double-checked what exactly recipients of the link will see, I was surprised to find "Anonymous Auroch" and a bunch of other weirdly-named critters visiting this page together with me.
A quick Google-search turned up some explanations on Blogger and on TechCrunch.
But these did not help me understand. Are there indeed anonymous users viewing this file that I have shared? How can this be, if I did not yet publicize the link?
