Book Cover violates FB nudity policy????

Today on Facebook I shared an authors book cover.  Didn't think anything about it, other than sharing a book by someone I enjoyed reading.  Then I got a message saying my image was reported as nudity.

Well this cover was created by the publisher, its available for sale on all sites... and we all know how much trouble Amazon is with nudity so...... WHY?

If you didn't like something wouldn't you just hide the post, or unfriend the person.  Seriously I doubt this is someone I even speak with.  If it is someone I speak with, then why??? They have to know how perverted and sarcastic I am.

What do you think of this cover?

Other than the fact that it is Changeling Press and I typically do not like their covers at all.  Just a personal preference though, it has no bearing on the story within or the author themselves. What is wrong with a character with a drawn butt? Its not like its an actual image!  

What do you think?  Two commenters will a copy of this book to support Anne Kane.
