The entire mood of the subreddit changed overnight from posts that vilified Sec. Clinton to posts that glorified her - it was completely crazy. I read that subreddit quite frequently during US election season and the difference was staggering. People dismiss it as "everyone rallied behind the nominee" - as someone who was there practically every day. It definitely wasn't that. There is definitely something shady going on with that subreddit in particular.

Incidentally, the TV news media was also seemingly doing a blackout of the fairly heated protests taking place outside the building where all the disappointed Bernie folks were trying to get inside. I only found out of them much later from online videos.
