Verifiable

Yandex's indexing robot for content in languages other than Russian, feeding the international yandex.com search index. Yandex's robot table documents that it can index content when there is no explicit robot-specific restriction, and lists it among the robots that do not follow the general robots.txt rules written for arbitrary robots.
