Efforts to reproduce "Navalny's texts from jail are not written by Navalny" claim and stylometric results.
We gathered some stuff manually, but also a sizeable share of our data comes from: https://github.com/norpadon/navalny (many thanks!)
See 'corpus' folder and other folders in this repo

So far, two strong candidates for “writings-from-jail” style emerged: 1) Navalny himself and 2) Maria Pevchikh. Likely it’s a mixed corpus.

Navalny_freevsNavalny_jailsamples show stable heterogeneity: there is similarity between them, but the difference is obvious, too.- When verified against potential candidates,
Navalny_jailexhibits mixed signal, bothNavalny_freeandMaria Pevchikhshow stylistic affinities with jail samples. - Overall, between-author relationships are muddied (e.g Zhdanov and Volkov show certain level of similarity), which can be a trace of editor/ghostwriter.
- Corpus needs more attention: 1) I can't rule out some systematic bias: what we might be seeing is a 'platform signal', not authorship. 2) We need more Y. Navalnaya's samples; we see she is similar to Pevchikh and Navalny, but not enough data to do proper verification. 3) Something is off about Sobol samples that come from large telegram data (duplicates?).
