Doxx or hold people accountable for what they say online?
If someone says something of their own free will then puts it in "writing" on the internet of their own free will should they not be accountable for things they say and did of their own free will?
Personally I suspect this might be a useful tool for teaching budding new internet users that they're not anonymous when they hit "send".
But like any tool that ever existed, the potential for abuse is definitely there.
I wonder if people who express this sentiment will still be doing so when the pendulum swings so far the other way. Will you also be grateful for a massive register that exposes everyone who ever espoused views in favour of LGBT, multiculturalism, etc in a society that condemns and even prohibits such views?
Perhaps there's some Middle Eastern theocracy where this scenario exists already. Are you glad that Saudi Arabian trans activists will forever have a target on their backs?
