Googlebot for smartphones found an increase in authorization permission errors
 

OK, I am seeing this for the first time. I've got email from google with subject about one of my sites:

Googlebot for smartphones found an increase in authorization permission errors .

Googlebot for smartphones has identified that an increased number of URLs on Teasing and Humiliation | Femdom Destiny cannot be accessed without permission. Specifically, these pages either present a login page for mobile users or return a forbidden response code (HTTP 403). As a result, mobile users might not be able to access your content at all, and Google might not be able to show your pages in mobile search results.

When I am logged into Google webmaster tools , I am seeing this below (first time in my life). WHo and why da fuck is trying to go behind wp-login page, I don't get it. Any advice?
Thanks
