The smaller problem is in those details—the scheme described is highly vulnerable to attacks like the following: I create a network of private bot accounts who post high-frequency generated content, and a follower account who follows them all and installs the browser extension. Whenever I want I can print money (well, Twitcoin) by uploading these fake hornet tweets to the new platform. I can think of ways to defeat this specific attack relatively easily, but I’m not sure it’s easy to defeat all such attacks.
