Observatory

Any advert in a public space that gives you no choice whether you see it or not is yours. It’s yours to take, re-arrange and re-use. You can do whatever you like with it. Asking for permission is like asking to keep a rock someone just threw at your head.

—Banksy, Cut It Out

A rip off occurs when the aesthetic rules of a work are copied by another. Aesthetic rules can be defined and therefore compared.
