I know this is about people paying for posts with money, but if one zooms out a bit to think about this -- any user of a platform like Twitter is paying/spending time (aka paying in their time and attention). IMO, trying to police and stop people from spreading their ideas online (political or otherwise) is a fools errand, and the antithesis of how social networks function.
What role do you think these networks should play in distributing these posts to our door?
