> This website habitually shadowbans people and controversial comments are hidden as if they never existed.

First off, enable showdead to see the shadowbanned users. I vouch for their posts sometimes, because sometimes they're good posts. But a great deal of them aren't really here to be a part of the conversation. It's not censorship, it's curation, and I think HN is better for it. Want trolls? Hit up 4chan or something.
