I've only referenced things that Makhnovists agree to, it's hardly the Bolshevik history of him. You can be extremely charitable in sourcing and still come to the conclusion that Makhno was mainly pathetic and harmful (though platformism is interesting). I also think that enabling actual genocide is a little more than "trivia", but it's not owning the tankies, so I can see why you would be uninterested in it.

Makhno did, in reaction to a rather brutal set of evidence that you can't just toss out arms and training everywhere and tell people to sort themselves out, fight at least some of the fascists he equipped and made a more pointed effort of helping the surviving Jewish people with community defense, but the underlying problem of him overwhelmingly serving to spread violent chaos in a state that had already been war-torn twice over remained, and that's part of the "banditry" accusation.
