CC is ofcourse up to you as the author but its really a thing you need to think through.
I dont care for CC, but not haveing CC is a thing you really need to think about. firstly a lot of people refuse to read a story with out CC
secondly the amount messages you will get about to please ad it, yes its really anoying but it happens a lot
you could always go half and have limited
beside do the looks really matter, I mean really would it mean anything to the story?
and if you dont have CC you really need to make up to it the readers. I mean art scenes body overlays and such.
