When trying to combat verifiable misinformation. We've got people working in bad faith to muddy the waters in democracies around the world, they're purposely trying to amp up the chaos in the social space and sow division amongst different groups.
I think if some people are found to be purposely spreading misinformation on a mass scale, there needs to be some sort of special punishment that restricts their freedom of speech. Maybe they're restricted from social media altogether, fined, or there's jail time, I don't know, but something should be done to weed heavy, repeat offenders (above and beyond just misquoting something or throwing out an opinion or whatever 90% of the population probably does).
Obviously, some guardrails would need to be put in place to prevent Trump or others from turning around and using that to silence critics or journalists, but at the same time, people/organizations who are heavily abusing our democratic system should be punished somehow. It's a really fuzzy line between a journalist just getting their facts wrong on a developing story vs entire news organizations that are purposely trying to misinform people.
