After briefly skimming that Wikipedia article, it seems like the phrase/battlecry has undergone multiple iterations over the years, originating as far back as perhaps WWI.

Could it be the case that fascist nationalists appropriated this aspect of culture to galvanize and accumulate support? Sure. Look at the Groypers with Pepe the Frog in present times.

That phrase hasn’t always been wielded by fascists, however, and it seems like the larger Ukrainian population have taken back this phrase from the fascists.

I think the .ml mod definitely had too heavy a hand with the ban here.
