I've personally found HN to be a lot more censorious than the subreddits I frequent. I really don't like the diverse fuckery the HN board software uses as "anti-spam" measures, like account creation IP bans ("Account creation temporarily disabled"), slowbans, hellbans and defacto bans that discard the content of your post and pretend to be temporary ("Too fast").
