It’s not clear to me how fingerprinting helps... eventually to defeat such protections, a nation state could develop virtual machines or botnets to trick any script into seeing their posts as unique. The newest trick is to amplify posts written by third-parties, for extra authenticity. I can see how this kind of service protects against “normal” sorts of abuses, but nation states can build their own Amazon Turk and at that scale, it seems impossible that a service like this would be effective for long. Sadly the only long-term defence of this might be to start slowly closing down the open internet borders, to make it harder for other countries to mimic a country’s citizens online. Similarly, countries have an added incentive to do this to spy on local servers. It’s possible that one way or another, we’ll all be living under a Great Firewall whether it’s government or corporate controlled, or both. Nation states hiding behind anonymity might just kill some of our abilities to be completely anonymous, that seems to be the trend here...?
