Not all review evaluations were positive. Eli Hawkins, acting as a referee on behalf of the Journal of Physics A, suggested rejecting one of the Bogdanovs' papers: "It is difficult to describe what is wrong in Section 4, since almost nothing is right. [...] It would take up too much space to enumerate all the mistakes: indeed it is difficult to say where one error ends and the next begins. In conclusion, I would not recommend that this paper be published in this, or any, journal."
