The charge could scale with audience size. For audiences of < 10K (or 100K), the fee could be zero to keep community groups from being charged. In some sense, this could be a proxy for compensating wasted aggregate human time -- or a tax on social media for (social) environmental damage remediation. (Of course, it's not "your" social media account causing damage...) My suspicion is that a long cool-down timer (e.g. every post takes XX minutes to launch) may be better. Something would probably have to be carved out for following breaking news (e.g. perhaps you get to punt the timer for 12 hours once a month).
