I'll be incredibly brief.
Creating hall monitors—maybe that's too cute—for information on social media probably won't deliver the results you want, and it will become a pariah for political actors, partisans and malign foreign actors to seize on.
As Ms. Jankowicz pointed out very well, you have to go after the technological amplification that helps distort the conversation. Botnets, for example, and malign and distorting algorithms are great conversation points and great places to start. Start creating consequences for platforms that don't clean up their act. That is going to be infinitely more effective in creating healthy domestic conversations that won't get polluted by money from the outside.
