from the article: Kirsten turned to federal copyright laws and found a section on fair use. Copyrighted work can only be used without permission when someone is criticizing it, commenting on it, reporting on it, teaching about it, or conducting research. Repinning doesn't fall under any of those categories. Couldn't it be argued that "pinning" something is an implicit endorsement, and constitutes 'commenting on' it? If that's not enough, couldn't they just add a comment and satisfy this? I am not a lawyer, please help?
