Tip: You can always tell if you are banned on Reddit by accessing the shadowban appeal page which is only visible if you are shadowbanned yourself:
replyNo, FB has their own shadowban system
replyReddit and HN.
replySince when does HN have shadowbans?

replysince almost forever, that's what the "show dead" toggle in your profile settings is for - it shows the dead posts from shadow banned people
replyI always assumed that those were posts that got flagged too often.
reply"Spamming", or rather, responding too quickly in an intense discussion, is cause for automatic shadowban here on HN. It happened to me on a previous account some years ago. The posts themselves were harmless, I merely responded to too many users in a too short timeframe. My attempts at having the ban undone also turned out to be a waste of time. Completely absurd.

replyI wasn't aware HN had it, but considering the number of [flagged] by people who work for big tech I'm sure some people actually posting truthful things have ended up on the shadowban list
