Personally, I don't think this was a complete/valid test - Yandex could be censoring other things. The input test data primarily covered things that would fit a specific narrative, not one for the 'other side'. Has anyone done a more complete test?
Can you give examples of queries for the "other side"? I'd like to test them out.
