That’s not at all the argument that was being made. I’m sure the grandparent poster would be more than happy for the content to stay up if they had the explicit consent of the people they’re collecting images of.
The images are not altered only cropped.
According to this logic when journalists crop a picture of celebrities they should ask for dress designer consent to not include the dress?
Some people like faces some people like feet. Why do we need consent for liking a certain part of picture?
