Jinse Finance reported that Vitalik stated in an article: Regarding this "displaying the country of account origin" feature, my predictions are as follows: In the short term, it will bring many positive effects. In the medium term, those with sophisticated means will find various ways to disguise themselves as users from other countries. For example, by renting someone else's passport, phone number, IP address, etc. Creating one million accounts with fake geolocations is moderately difficult; but creating a single account with a fake location and quickly accumulating a million followers will be very easy. Six months later, those political bot accounts that actually originate from (any Eurasian country)—with names like "Defend Western Civilization"—will all change their location tags to "United States" or "United Kingdom." (The above is what I think will happen, not what I hope for. What I truly hope for is: (i) We can gain a clearer understanding of how people from different communities view various issues, and that such insights are not easily faked; (ii) The "community" here should not be limited to a few highly explicit and easily verifiable identity credentials such as nationality or university degree, but should be a broader, more emergent group identity that can integrate information from multiple sources. But I believe that building such a system that can withstand adversarial attacks is by no means an easy task.)
