HN has always been a curated/moderated site. I'm not really sure what "censor" means other than that, at least in the context of an internet forum like HN.

We basically moderate posts that break the site guidelines (the ones that we see, at least).

Is there a particular post that you feel was censored that should not have been? I'd be interested to take a look.

If it's almost non-stop, it should be easy to link to a few examples, no?

probably half of my comments are flagged or reported. that's censorship. look at the comment history yourself and stop censoring people.
