I'm not sure how that's a problem. Presumably I like the sources I deem to be of a certain quality. I don't want to see the stuff I don't like because it's probably not at the standard of quality I expect. The reason nobody's solved the "moderation" problem is because it's the wrong abstraction or the wrong problem to solve. The problem to solve is how to make filtering and discovery better.
