I don't know. Can you style deleted/removed comments with a subreddit's style sheet to hide them?    If I went to an askscience thread or something and saw only the 'approved' answers instead of pages of deleted posts, I'd probably actually read it. Instead I see an intriguing question and after 30 seconds of scrolling and seeing a bunch of out of context posts and deleted comments I give up. If I really care I'll google the answer.    This way if you cared, you could turn off the subreddit's CSS and see all the deleted posts, or you can keep it on and be blissfully ignorant and just look at the actual responses.
