There are "Official Rules" and copyrighted material is forbidden. Hit the flag and flag it. I've seen accounts getting blocked and frozen for doing it.
We depend on the community to self regulate this behavior. That is why we get rewards for curating.
I was not aware of that. I looked in the terms of service, but didn't catch that. Thank you for letting me know!
