Роспотребнадзор actually translates to Consumer Protection Services.
ok thank you. I actually mostly know russian, but that word made no sense to me.
I know Bulgarian, which is similar. Роспотрепнадзор derives from Russia (Россия) Consumer (Потребител) Supervision (Надзор).
I think "decision maker" means they are acting on some sort of a complaint/request. Rospotrebnadzor ("Ros" - Russia, "Potreb" - Consumer or Consumption, "Nadzor" - Oversight) is simply the government org whose responsibilities include blacklisting. There is no way to tell from that website what led to this decision as far as I can tell.
