Possible to upload photos marked with incompatible license metadata fields to photo directory

[sarayourfriend]

I uploaded a photo earlier this week (​https://wordpress.org/photos/photo/12962a0b7f/). It was approved a couple days later, however today I was editing photographs taken with the same camera and realized that I actually have a copyright field configured in the camera to add a CC BY-NC-SA 4.0 metadata field to every RAW file produced by the camera. My photo editing software keeps these in the generated JPEGs. I confirmed that when downloading the image linked above from the photo directory and inspecting the metadata fields in GIMP, I can still find the CC BY-NC-SA field on the image.

I'm not sure what my recommendation for a fix is: either moderators could be tasked with checking for these kinds of fields or these fields could just be automatically wiped from uploaded images. However, it seems like the first is probably the correct option as it would prevent illegitimate (incompatibly licensed) uploads from making it into the directory in the first place.
