If the strongest "evidence" is anecdotal reports that pro-Russia posting on Reddit decreased that seems more like Redditor confirmation bias and delusion than proof of a propaganda bot farm co-located with Yandex
> Ukraine Is Successfully Bombing the Heart of Russia's Disinformation Machine
Proof from within TFA:
> Yandex is the Kremlin’s information machine. It answers about 70% of search queries in Russia
> The director of Yandex News resigned in 2022 and called the company “a key element in concealing information” about the war
> the assistant inside Yandex Browser, which has 71 million monthly users, in a 2026 study by the research group Policy Genome found Alice endorsed Kremlin narratives in 86% of its Russian-language answers
> Cloudflare, the internet security company that fronts a large share of the world’s websites, measured automated requests from Yandex’s network at 0.4% of their two-week peak after the Vladimir strike
So, it’s used by most people in Russia, it regurgitates disinformation, and the attack seems to have depressed its use.
Sounds good to me - what are you missing?
However there was a flurry of posts that troll farm (conflated with "bots") activity dropped and consequently support for parties/people/politicians they don't like has dropped. Which ironically was propaganda.
