X (formerly Twitter) has rolled out a new system that displays the country an account is posting from. Officially, the goal is to fight misinformation. But Ethereum co-founder Vitalik Buterin argues the update may do the opposite. He shared a detailed critique in a post on X, warning that the feature is easy to exploit — and dangerous for vulnerable users.
X now shows a public label indicating the country an account appears to be posting from. At first glance, it seems harmless — maybe even helpful. But Buterin says the system is fundamentally flawed for two reasons:
The result? Millions of ordinary users get labeled accurately — while sophisticated actors can pretend to be from any country they want.
Buterin predicts that X’s country labels will work briefly — then collapse as propaganda accounts adapt.
The system doesn’t use GPS. It guesses your country based on:
All of which can be spoofed using:
His prediction: Within six months, non-Western propaganda accounts will masquerade as U.S. or U.K. users, completely undermining the system’s purpose.
After thinking further, Buterin sharpened his criticism. X is exposing location signals without user consent, and without any option to disable the feature — not even by deleting the account.
For everyday users, that’s annoying. For high-risk users, it’s dangerous:
Even “a few bits” of extra data, he says, can narrow down someone’s identity — especially in regions where speaking freely carries consequences.
His description was blunt: “a retroactive rug-pull of user privacy.”
He’s not opposed to transparency. He just believes X’s approach is naive and dangerous.
The system he imagines would be:
He admits this would be complex, but argues it’s the only way to avoid weaponizing identity metadata.
Tech platforms are under pressure to fight misinformation. But Buterin reminds the world that transparency without consent is surveillance.
X’s update highlights a deeper tension: Platforms want clarity. Users want safety and control.
And as privacy debates intensify, even small design choices — like a country label — can reshape the digital battlefield.
X now shows country labels for all accounts. Vitalik Buterin warns the feature is easy to spoof, will be gamed by propaganda networks, and exposes vulnerable users without consent. He argues it’s a privacy rug-pull that risks doing more harm than good, and calls for a more nuanced, opt-in, tamper-resistant system.
