I suspect that 21e8g6 is an expanded version of the source image which is smaller with generative AI, (I also flagged it but accidentally sent it off not finishing my reason/description), as there are clear lines of suddenly blurred areas.
Looking at the uploader's profile, which contains a link to a website that I would say would hint towards other of their uploads also being AI-generated, (it provides image generation), as they look off.
Since AI stuff is getting banned I thought to draw the attention to it, and sorry for my mistake with the report.
