Superman makes for great stories, as long as you don’t focus on his power. You can’t beat him with physical strength, so stop trying to write strong villains. Probably stop writing villains at all. What Superman struggles with isn’t physical embodiments of evil, it’s the good intentions paving the way to hell. You can’t punch a person with good intentions for their bad outcomes. It’s hard being the ultimate arbiter of good in a world of complex morality.
It could be a relatively small number of users all making a disproportionally large number of posts. Like a single Minecraft streamer with too much time on his hands.
