Re: What about abuse of fair use?
Yes. And it gets more complicated than that because "fair use" is the American rule, where other countries have other rules. here in Oz, for example, we have "fair dealing" which is more restrictive than US "fair use" in some respects, less restrictive in otrhers. So there are lots of different "fair-somethingorother" rules, and even where you have the same rules, they are often interpreted in different ways in different places.
It's a mess.
