`YandexPartner`

Yandex says YandexPartner downloads information about the content of Yandex partner sites. The robot list says it does not take the general rules in robots.txt into account. The page does not name an advertising product for this token. YandexDirect 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.
