Even if they somehow implement this in an anonymous way (let's be real, it's the government), it would have to be through government services and a lot of people that use social media, specifically Indigenous people, well, let's just say, do not trust the government. So, if this is implemented in a mature, reasonable way without any involvement from the private sector; you are still excluding a significant portion of the populace just by having the government involved.
This should never have even been brought up. It's idiotic.
