I'm not able to know how often it could prevent such slander in those times, but we can look at the incentives. In those times, the authorities (church, newspapers) had central control over the main narrative, which is still mostly true today, but is beginning to fall. Back then, it seems you could slander minorities and there was pretty much no way for minorities to defend against it. In contrast, the upper classes had a means (duelling as an example) as an incentive against slander, and that imposes a cost on it. On social media there is no cost to publish lies. Verifact seeks to impose a cost on lies because you need to have something at stake. So I think if it existed at the time, Verifact would make it more costly to slander minorities, and it would be more profitable to disprove all kinds of pseudoscientific beliefs such as racial superiority and Nazi eugenics. Of course though, Verifact requires access to communication channels and tokens and that wouldn't be viable in those times.

> authorities of their own choice, one could easily choose more forward-thinking judges

Yeah could be interesting. I'd just want to make sure people don't create echo-chambers or follow others based on political opinions rather than facts. Perhaps letting people 'invest' in the judgment decisions of others would help, and you'd get notified when they stake.

I want to avoid discussing "echo-chambers" as my views on that topic make me sound like a knee-jerk contrarian. So I'll wish you success here, and thank you for your efforts :)
