Article Does Not "Significantly Expand" - Much is Just Summary, Very Little New
Reading the article, ~75% of it is merely repeating usecases that already exist and are explained by Kleros staff in blogs. Summarizing is not "expanding". Furthermore, looking through the author's other articles, many are very similar, in that they consist mostly of basic Kleros information, but translated to Russian.
If this really was reaching a new Russian audience, that may be fine, but look at the interactions for his other articles: many of the exact same names appear, which makes one believe that he shares it among the same group of a few people every time. If either were true, in which the article was genuinely expanding with clear effort put in, or if it reached a broad new audience, it would be fine, but neither apply. Thus, as it does not meet the interactions or "significantly expands" criteria, I believe it should be rejected.
I suggest the jurors download the Google Translate extension to read the article. Attached is evidence showing the same few people interacting with the article.
