You don't need them (other than a basic level for legal compliance). In fact, most social media does not have moderation in the sense we see in Reddit. What the Reddit model provides, and your example lacks, is a shared reality. There is a bit of variation with comment orders (both different view modes and some fuzzing); but for the most part, two users viewing the same community at the same time see the same thing. Without that type of shared reality, it is essentially impossible to build the type of community/unique subreddit cultures we see in Reddit today. Most social media doesn't do this. HN does. Twitter and Tumblr operate operate as more of a social web. Most content gets spread by users reposting it, propogating it through their network. In that way, the accounts you follow act primarily as the "moderators" for your view of reality. No two people see the same reality, and it is incredibly difficult for distinct subcultures to emerge; and even more difficult to participate in multiple subcultures, as your view of reality does not distinguish between them. There is also the TikTok model of a super-charged algorithm employing black magic. Or Youtube's model of algorithmic discovery, combined with meaningful subscriptions to particular creators. The other question is one of labor. The motivation for most moderators in Reddit is control over a community (which can be either a good or bad thing). If you take the community away, then all you are left with is unpaid labor. Unless you can have individual posters say "I want to post to the moderated list X", in which case you are back to the original model. Most reddit communities have policys restricting cross posting, and "brigading" across communities is generally not allowed by site-wide rules. Having a model where your content goes to everyone, and is then blacklisted by specific mod lists is essentially auto-brigading everything by design. Again, this is not nessasarily a bad thing. Plenty of social media does it this way. But it is meaningfully different from how Reddit works.
