Fully agree. Is upscaling just banned now, or what?

As draco said, using GAN upscaling or other sharpening tools isn’t forbidden, but in most cases, they make things worse by warping and distorting any already emerging, but pasable anatomical issues. If your image is already good, GAN upscaling isn’t necessary. if it’s not, GAN upscaling won’t fix it.

Furthermore, we evaluate images in their original size, so if you upscale your image to 4K, we will look at it in that resolution, and it will be judged as a 4K image.

If a poor-quality original image is combined with upscaling, it usually leads to multiple errors.
We don’t provide a detailed explanation for the deletion of such images, mainly because we’ve likely already spent more time reviewing it than the creator spent making it. And sadly a lot of uploaders wont ever try to fix the issues and reupload a corrected version.
However, if you have questions about the deletion, we will gladly address them, and will be looking forward to your new version.

Your last image was removed not only because of poor upscaling, but also because of the character's arms ending in weird stumps. If you wish to argue it's acceptable for a goo girl, you can appeal the decision, and it will be reviewed by Draco for a final verdict.
