NATO on bots, sockpuppets, and shills manipulating social media

NATO has a new report, "Social Media Manipulation 2022/2023: Assessing the Ability of Social Media Companies to Combat Platform Manipulation".

Buying manipulation remains cheap ... The vast majority of the inauthentic engagement remained active across all social media platforms four weeks after purchasing.

[Scammers and foreign operatives are] exploiting flaws in platforms, and pose a structural threat to the integrity of platforms.

The fake engagement gets picked up and amplified by algorithms like trending, search ranking, and recommenders. That's why it is so effective. A thousand sockpuppets engage with something new in the first hour, then the algorithms think it is popular and show crap to more people.

I think there are a few questions to ask about this: Is it possible for social media platforms to stop their amplification of propaganda and scams? If it is possible but some of them don't, why not? Finally, is it in the best interest of the companies in the long-run to allow this manipulation of their platforms?
