Even if you're half-joking, there's a very real point to this. It's really not solving the problem. It's moving it very so slightly down the line.

I'm not entirely sure how I'd want to word it, but it would be something like: It is prohibited to profit from engagement generated by triggering negative emotions in the public.

You should be free to run a rage-bait forum, but you cannot profit from it, as that would potentially generate a perverse incentive to undermine trust in society. You can do it for free, to ensure that people can voice their dissatisfaction with the government, working conditions, billionaires, the HOA and so on. I'd carve out a slight exception for unions being allowed to spend membership fees to run such forums.

Also politicians should be banned from social media. They can run their own websites.
