What about regulating advertising more strictly? I.e., if you couldn't do cpm (cost per impression) ads, all that increased traffic and engagement doesn't matter anymore, or at least matters much less. Or, limiting advertising entirely in a political forum - that would also render all that additional traffic moot. As a result, these sites would have no incentive to hosting any political content. I know it's implausible but maybe that's a direction to look at? Instead of limiting the content (free speech issues,) limit the motivations for facilitating such discourse.
