The problem is I don't want to finger point. 
But I would have assumed that if there was a policy on child nudity it would have been across the board. As such I would have expected a response from Site Admin rather than from store or gallery moderators - because surely any policy is laid down from above. At the same time I would have thought that anyone here would be able to guess fairly accurately which merchants were being referred to.
How can you show a naked image in the Store but then stop someone using the same morph in the gallery?
I don't know why you have the rules against some naked images - I assume it has to do with child pornography and if that is so then surely some of the images in the store could also come under that same umbrella?
