I have blocked the some of the URLs from robots.txt. I think there is No way to access the blocked URLs from my website. But I have seen in my logs, whatever I blocked the URLs from the robots.txt are crawled by Google bot. And also observed "Google bot" triggering the first request followed by "Mediapartners-Google". But I don't have the clarity that whether Googlebot crawling from any other leak or from "Mediapartners-Google".
And I want to know the relationship and differences between "Mediapartners-Google" and "Google bot".
