Users are already planning protest art. I personally wouldn't encourage people to join because it's more traffic for Reddit, but that's just me.
On other news, apparently requesting a subreddit now requires a 28d old account with 100+ karma.
EDIT: it's on again, since 20min ago:

EDIT 2: better view:
I think that the meaning of the sentence in German up there should be rather obvious. It's on-topic.
What's the over/under on how many "fuck /u/spez" there will be in the final piece?
My guess is that at least 10% of the canvas area will be "fuck u/spez".
