Or the entire opposite direction, ensure that it's not possible to get paid for shitty content. Kill the web ads market by legal restrictions to tracking and targeting ads, facilitate ad blockers everywhere.

Kill the money, and the commercial SEO crap goes away, and only the enthusiast content stays - as it was in the 'good old days' when simply getting clicks on your site could not get you any money.
