## Summary

Vitalik Buterin says that revealing a user's country without consent and without any opt-out, not even an option to stop using the account, is wrong. He says that while revealing country leaves a very large anonymity set in most cases, some people for whom a few bits of leakage are risky should not have their privacy retroactively removed with no recourse.

I thought about this more and I think responders are right that revealing the country non-consensually without offering any opt-out option (not even "stop using your account") is wrong.

In most cases, revealing country still leaves a very large anonymity set, but there are some people for whom even a few bits of leakage are risky, and they should not have their privacy retroactively rugpulled with no recourse.

**misha**: Now is CT finally going to make the jump to FC? (Prob not I guess.)

**tim**: I don‘t really like his way of arguing that gaming the system is inevitable. I‘m pretty sure Twitter also considered that this system would be gamed and they will try to improve it too.

But yes, it sucks that you didn‘t get a chance to opt out. Or, idk, at the end the feature was announced for many weeks and so one could have deactivated their account before.
