Eh. I disagree with both other commenters. It's fine to use AI in your process, but the author's voice is important. AI slop in and of itself lacks the context of the human experience to really understand humor. But it can come up with an idea that a human can improve on.

Up and down voting is the right solution here rather than banning. AI slop will get downvoted to oblivion, And even good AI content will be skewed more negatively than completely human art.

That all being said, if mods want to ban it based on preference go ahead and someone will likely just create a board where it's allowed, and people can self-select what communities they want to be a part of.
