The Matryoshka campaign takes a different approach.

Instead of sharing the fake news pieces themselves, accounts re-share posts from other accounts in the same network, and post them directly on the feeds of known fact-checking outlets. These “reshares” are formulated as a fact-checking request.

The accounts simulate the behaviour of a typical social media user, who might be sceptical of a piece of news, and would like the opinion of a trusted fact-checking source.

However, this process of resharing is repeated by other accounts in the network, ad nauseam. The “stacking” of posts containing false news reports is akin to how Matryoshka dolls operate, which is where the campaign gets its name from.
