My suggestion here would be to remove the default criterion for which posts are visible, so that per default all posts are visible (irrespective of the downvotes), but that people can select in their settings a threshold of votes a post should have in order to be visible.
Our proposal for how this would work is that all posts would be visible on personal blogs, but that posts with a negative karma score wouldn’t show up on the “frontpage” (the default view). People would still be able to see it on the “All posts” view until the post reached −5 karma, and would be able to upvote it back onto the frontpage. Sometimes this might lead to us losing quality posts, but it also helps prevent users seeing very low quality posts (e.g. spam).
