`YandexMobileBot`

Yandex says YandexMobileBot defines pages with layout suitable for mobile devices. The robot list says it does not take the general rules in robots.txt into account. The page's example is User-agent: YandexMobileBot and Disallow: /private/*.txt$. YandexMobileScreenShotBot is a different token. The robot list says an agreement between Yandex and the site owner can override some robots.txt restrictions. This check does not apply that agreement.
