I wonder why they are flagging you. None of my Aurora images have been flagged. I don’t think I’ve had any of my nightscapes flagged. I may be shooting in the dark (pun intended), but try putting a clear watermark on it. I put my photographer name at the bottom of my images, and I wonder if that’s preventing them from being flagged. I’m guessing the ai flagging is being done by…ai. So having an artist name on the image may stop the issue. It’s bizarre they are flagging yours.
