I've just stumbled across a user who has added over 400 nonsense/personal quotes (as far as I can tell) that should probably be deleted. I've done some, but it's such a huge amount that I figured I'd post for other bored librarians. Rather than link to the user in question, which I know is frowned upon, I'll just link the various "authors" he/she's posting them under:
https://www.goodreads.com/author/quot...
https://www.goodreads.com/author/quot...
https://www.goodreads.com/author/quot...
https://www.goodreads.com/author/quot...
https://www.goodreads.com/author/quot...
https://www.goodreads.com/author/quot...
Additionally, maybe a member of staff could send this user a "WTF/please stop doing this" message?
