Likely a hoax, but...
...interesting nonetheless -- I mean, how could a story about a high school girl running a library of banned books out of her locker* not be an interesting story? Add to that the discussion in the comments about truth vs. fiction and whether or not it matters, whether a hoax (if it is a hoax) could inspire people to Stand Up and Act or whether it detracts from real cases, and you end up with a good fifteen minutes of entertaining thoughtfulness.
And those thoughtful conversations take place in and around a bunch of people fighting about the amateur librarian's choice to not include Twilight in her collection, so there's that, too.
*Obviously, if it isn't a hoax, the girl is totally my hero.
