There are also a ton of ongoing news stories and stories in that past which were completely censored off HN. I cannot talk about them or link them here, but please know that they exist.
Why not? I'd like to see them. I also think that if you're going to make grand claims like that, you should include links so that readers can make up their own minds.
What if you create an article listing all of them, submit it to HN and post a link here in the comment? I routinely check dead links to see why a few people found it so controversial to censor it. I'd say 80% are true positives - spam, SEO junk, or some utter nonsense. The remaining 20% is content that is controversial to some people for some reasons. I learned quite a lot from it. There are days when this censored content is more interesting than top submissions.
I also happened to submit one such article somehow. I found an article on BBC saying things that are controversial today. It was flagged very quickly. It was interesting to me because BBC is a relatively reputable source and they don't publish junk.
