why is she posing nude?

Seems, except for the end of your comment you have answered yourself, "her poems are erotic..and she is probably using sex appeal strategy for promotion" I do not get how this has anything at all to do her being "a perhaps pervert". If a naked back is an indication of a perversion, then I guess all those people that go to the beach or swimming pool and expose their backs are "perverts". I just do not get it, and don't even want to try to understand how you can see her picture as a perversion.

poets should do poetry..no need to become a pornstar
