I keep thinking about this idea of figuring out a forum format that has checks in place to ensure that every participant is an actual human, as opposed to an automated bot.

I have had a ton of crazy ideas for how I would execute it, ranging from simply requiring to have government ID to requiring to have webcam on while using the website (to collect biometrics).

I am interested to hear from the community if (however crazy or restrictive, sci-fi) ideas that would allow to create a forum online that's only for humans.
