There are many topics in the Economics board regarding the economical effects of the war, would they fall under this rule? Or topics in Bitcoin Discussion about current stance of Bitcoin in Russia or Ukraine. Or topics in Speculation about the effects of war on the price. IMO such topics usually don't have "sensitive political agenda", but those who reply to them might have one.
I would say that there is a significant difference between the discussion of economics and the "sensitive political agenda" (especially about the current war). the replies you mean are nothing but offtopic spam, all you have to do is ignore them or even report them to the moderator.
I respect this decision of the campaign owner.
