We have reached a point where human-made images are being lost in a sea of low-quality AI-generated images, so as of now, any AI-generated content must go in threads separate to human-created content, with the appropriate tags applied. This means all types of media (images, video, audio) and text. This rule only applies to new posts.
If you think someone is breaking this rule, flag the post and move on. Do not start arguing over whether someone is trying to pass off AI-generated as human-made.
