It's a moot point. I very much believe in copyright, but you can't just put info in the public domain and yell, "Take a look but don't remember/retain it" in the name of copyright. If I redistribute it or reuse it for commercial purposes without your consent then maybe there is a case. But if I am just scraping it, i.e remembering it... Come on now.
Otherwise everyone who gets the lyrics to copyrighted songs or memorizes them and sing them in the shower is also in violation of copyright. Which would reduce the whole copyright thing to ridiculousness.
