There's a good reason for this - which the "mods die" post does somewhat outline.

As part of the mass purge of NSFW posts and changing the policy, the sub was set to "manual approval" of all posts, meaning for any new post to appear there, a mod has to manually tick that it's okay to let it through.

And they banned three of the most active mods at the same time.

When I posted that image, it was held in a queue for about 30 minutes, and then suddenly 30 posts appeared all at once, (presumably a mod logged in and cleared out the queue) - then nothing for half a day.
