The only way to generate a human-only net is to figure out how to remove all economical incentives from there. The “golden age of the internet” a lot of people, including myself, are nostalgic for had very very little economical incentives. I missed usenet, but I remember being active on small forums in the late 90s and early 2000s that were almost entirely passion projects. I recall a huge controversy in one forum when the guy who was maintaining it asked if it’s ok if he puts a banner ad at the top because someone was offering him $200 to advertise another forum.

Removing the economical incentives is very hard though. Even HN is gamed by many tech companies and projects. Reddit is obviously a lost cause. It’s a sad state of affairs, but I don’t think there is an alternative.

Lose anonymity and bring back key-signing parties. Maybe you can't guarantee that everything is human-generated, but at least you know the chain of trust that leads to the human that signed off.

Yes, I'm aware of the irony of creating a darknet that only works by removing anonymity.

The golden age of internet was during seo, what are you talking about?
