That is a hard question. I've been giving it some thought since I posted that comment. I don't think moderation is a good idea and I would rather have the open market dictate the posts that float to the top. I think the current system works for filtering low-effort spam and I would like it to continue that way. One reason why I dislike reddit is that its structure is conducive in creating echo chambers where the "most popular" opinion for that particular subreddit floats to the top and any dissenting or controversial ones fade into their own small bubbles. The idea that I'm thinking at the moment is to not let the amount of stacked sats dictate the position of a post in any shape or form and only sort posts by their most recent activity. Clicking that lightning button should just be a form of "Thank you for your contribution to the discussion"-kind of thing and anti-spam. That way, people will not game the system for profit.

Clickbaity links aren't rewarded with sats unless the user decided to tip based only on the link title, which I think is unlikely, simply sorting by tipped amount should filter out all the noise.

In terms of moderation, I think it would be good to do something along the lines of the "Orange Checkmark" in that users post sats to get "Verified" and through that mechanism allowing the community to enforce moderation.
So for instance, you need to post 100,000 Sats to get verified, and if you break the rules of the forum people can report you. If it is found that you did break the rules, you will be docked sats from your verification. The docked fee could then be split amongst the reporter and the platform in order to fund the moderation at the platform level and incentivize reporting at the user level.
This could be implemented for both the posts and the comments and would likely take care of the vast majority of spam.
