`YandexCalendar`

Yandex says YandexCalendar is the Yandex Calendar robot. It downloads calendar files by users' requests, and those files are often located in directories prohibited from indexing. The robot list says it does not take the general rules in robots.txt into account. The page's example is User-agent: YandexCalendar and Disallow: /. 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.
