Very suspicious. Something strange is happening, at least two subreddits on my radar have just unexpectedly reopened with unusually positive comments heavily upvoted despite being against the tone of everything before, I've seen others reporting similar.

Edit: Also, a thread was originally posted by someone questioning the opening up, it was quickly hidden (it got supportive replies) and is now locked. Edit again: in less than an hour there have been several such threads that have vanished.
