Also I should add that I had this conversation with the Goodreads help desk earlier (support@goodreads.com):

As we mentioned, we remove fan fiction pieces at the request of authors. If there are any works you're concerned about, the authors are welcome to contact us and we'll take care of it right away.


So that belligerent "Experiment BL626" librarian on Goodreads is completely wrong. He should be removing the fanfic entries, not arguing ceaselessly that they have every right to be there.
