I don't get it. Are there ways to hold people accountable for misinformation in real life? Say, if a politician lies to people during a speech. Are there any regulations that apply to that? But if they lie online, that's not okay? Or are politicians excluded here and it only applies to regular people? While it seems like a great cause, I'm afraid that the collateral damage will be far too great.
