My issue with lack of moderation in social media is not the political polarization. My issue is the blatant scams pushed by bots, or by questionable companies paying sub celebrity influencers.
Criminals are not willing to have rational conversations. But they just won a free pass from the platforms.
Fraud is a pretty clearly defined crime. Fact checkers weren't demarking scams and bots.
Bot activity is best handled through system pattern matching, not correcting political cartoons.
You also assume that the people doing the fact checking are better informed or otherwise better people than those with the access to propose and vote on community notes. This is unsubstantiated at best.
