That's his site now from your link, I went outside of archive.org straight to the site and he's storing his reviews off platforms there. Since he's alone making the site, the search feature is hit or miss but he has interesting book reviews in the recent section like: https://www.jewsandpolesdatabase.org/2020/03/15/double-genocide-valid-holodomor-was-genocide-holodomor-jewish-complicity-kulchytsky/ where he summarizes a few of the author's points going over the objections by holocaust supremacists to recognition of the Holodomor as a genocide.
