I believe networks of human individuals can solve this to a good degree assuming a particular topology exists. Like, imagine a group of professionals of decent sized, all specializing in a similar field, and having lots of strong connections between each other where they have ample opportunities to share information. It would be hard for an outsider to come in and astroturf their product without immense effort (like hiring shills to attend conferences). In-person networks also obviously solve the problem stars as reputation: reputation spreads naturally in these sorts of networks. I think the problem comes with algorithmic scale. Maybe a solution would be to have more community building activities (maybe preferably offline).
