HN and Reddit (obviously depends on a subreddit) are drastically different communities than LinkedIn, Twitter or Facebook. I might downvote on HN or Reddit if something is spammy or blatantly doesn't bring any value to the conversation. I do that very rarely though. Frequency wise I much more often go straight to reporting content for removal without getting into discussion with people that have more free time than me. While it still unfortunately takes time, I believe that if damaging (racist, abusive, calling for violence) content is left unattended the general amount of it will only multiply with time.
