DALL-E threads seem to truly be protected. There was a Pragmata/loli thread earlier today. There was nudity up for hours; at one point mods deleted multiple posts at once but it didn't seem like the thread was ever formally deleted. In fact, it seems to still "exist", even though yout can't see it in the catalog. I mean, it could be a bug but still. Just a headsup when it comes to future threads.
