And the news traveled pretty quickly to so many different subreddits before the ban wave. All the subs that had a chance of getting banned were making posts warning about an upcoming ban, and I even saw a post in r/againsthatesubreddits like 6 hours before the banwave that was talking about the post on watchredditdie in a way that sounded like they knew it was true.
I highly doubt that all these mods just saw one post from a medium sized subreddit and started preparing for a ban. Seems to me like all the mods within certain subreddits knew and it got leaked to other mods.
