Another issue Reddit abd Facebook seem to have is that in trying to host a legion of communities under a single umbrella they wind up having to moderate a mishmash of communities that are at best poorly understood by the higher ups (cultural differences and linguistic barriers, chiefly), and at worst are actively hostile to each other or even hostile to the platform itself. It's rather remarkable they even function at all.
