That explains it why /r/science is such a graveyard! Thank you! It sounds like if any of the 1500 mods dislike a comment, then that comment disappears. That's extremely biased towards removing comments. My suggestion would have those 1500 mini mods vote "keep" or "remove" - majority wins. The main mod can look at contentious votes and override the mini mods decisions. Further the main mod can remove mini mods that are voting poorly.
