I feel like a lot of people are only reading your question and not the rest of your message. The problem with what you're describing creates a lot of duplication of effort, while also creating this weird community that's fragmented yet all in one place, and also creates a lot of work for moderators. Using reddit as an example, say you have a game, with a dedicated subreddit for it at /r/game. A lot of people decide they don't want it filled with shitty memes, the moderators have everyone take a vote, and they decide to spin off memes to /r/game_memes. It sounds like your example would instead rely on people basically choosing specific moderators to curate the sub, and you only see the results of actions taken from moderators you "subscribe" to, effectively. This would rely on moderators having to manually watch the sub for memes, and if a mod sees a meme, they remove it, and if you're not subscribed to an anti-meme moderator, you would not see the result, and would still see the meme. Can you not see a problem with this setup? You're relying on moderators to flag the memes. You could let users flag the memes on their own, but then you get people abusing flags. It's best to just let moderators be what they really are -- not curators, but janitors. Moderators keep a community clear of abuse and spam. Yes, some subreddit moderators have extreme power trips and ban people for the stupidest shit, but there's not much you can do about it. Your solution just creates a ton of extra work.
