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.

I find it stunning that they’ve decided to go ahead with this. Why the need for a 2023 r/Place when there was 5 years between the first and second? What the hell?
Because they are seeing the threat that places like Lemmy are providing to users. They need to draw people back to Reddit and distract from the protests that are still a topic.
