IMO the only way to accomplish this is to require a fee for every post. Different platforms might have different fees. If Lyn Alden is posting alpha, perhaps she would pay .0001 bitcoin with the expectation that she would receive more than that in value back. If we’re just shooting GMs and GNs around the horn then it would cost less but the quality of content would go down.

Ultimately we’re fighting that information is “free” from a marginal cost of production. So if we’re worried about the good information being lost in the clutter of the other information, then we need a financial “proof-of-work” to post. It would probably include a subscription model of daily expense to consume as well.
