By all accounts it seems like there was a major reshuffling that took place on the night of the Democratic National Convention.
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.
Yeah I used to enjoy the sub too, some interesting discussions that were usually polite. You are 100% correct it was overnight, there was nothing organic about that.
> they did the exact same thing at the exact same time.
They did not do the "exact same thing" at all. You are spreading lies using logical fallacies and that causes harm to the community here; please stop. Your false equivalence, presented without evidence, is harmful.
