Suppose you run a message broadcasting service hosting three hypothetical world leaders. One posts propaganda about an ongoing genocide in his country, namely that the genocide is highly beneficial to those being genocided. The second posts racist messages threatening another country with annihilation. The third posts that his recent election loss was "stolen," and subsequent to these posts a few of his supporters stage a riot in the capital (without coordination from the leader). Which messages do you allow? Which do you censor? And which world leaders do you ban?
