If bots are being used to create chaos in society, it really isn't possible that the platforms themselves are just innocent bystanders here. It is technically possible and quite easy for the platforms to block bots if they really wanted to, in fact it's actually in their best interest to have human only organic activity as it increases the platform's credibility and reduces network cost. If they're still letting bots operate and actually post content on their platforms, they're likely in cahoots with the politicians.
