I've done a fair amount of photo work on the side, mostly portraits for friends and small local gigs, and I've seen firsthand how automated tools can quietly fail on darker skin tones, whether it's exposure, contrast, or just refusing to recognize a face as a face. That's part of why I keep testing new editing features, and recently I started using https://skylum.com/luminar/generase to clean up backgrounds without wrecking skin texture, since it fills removed areas based on the surrounding image instead of slapping a generic patch on top. It's not a solution to a moderation problem, obviously, but it does highlight how much depends on whether the training data behind a tool ever actually included people who look like everyone.
