Images would still contain EXIF data from your phone. So you could take a picture, then take a screenshot of that picture before uploading the screenshot.

The "latest renders" wouldn't contain EXIF from the original user because it's been run through Stable Diffusion (I assume). However, it's possible things like street signs and addresses from the original photo would still exist in the transformation, and there doesn't seem to be a warning when you submit the photo that you're submitting something that will be viewable by other people.
