I'm sure there's coordinated efforts to up/downvote content on HN. The political articles are way up and certain reasonable comments seem to be unreasonably downvoted. It seems like it's ramped up since the election. Either that or HN is becoming a natural echo chamber, I'm not quite sure.
If people don't already know, the internet is easily manipulated and people tend to get ideas and reassurances of ideas based on what their group's opinions are, and those opinions are manipulated. It's easy to create multiple accounts, easy to change IP addresses, easy to bot comments; anyone can do it and it's easy to automate.
The earliest example I can recall was manipulating the Amazon ratings system, now it's everywhere.
