 Matryoshka bots tagged fact-checking organizations and asked, I see this kind of news every day. The official channels are silent. What should I believe? To most people skimming the web, the question seems innocent enough. But what Matryoshka was trying to do was use these bots to convince fact-checking organizations to actually look into a fake story, which not only gave those stories traction, but sent fact-checkers on a wild goose chase. Hmm.
