Facebook has threatened action against Sydney jeweller Victoria Buckley for posting pictures of a nude porcelain doll posing with her works.

The social network issued six warnings this week to her, saying the pictures of the doll, which show little more than nipples, constituted "inappropriate content" and breached the site's terms of service. It announced that it would remove the images of the doll.

Buckley said she has been using the same dolls in her shop window but has not had any complaints so far. The dolls are high-end porcelain figures that designed by Marina Bychkova of Enchanted Doll in Canada. They are featured in art and culture magazines all over the world.

Buckley charged Facebook of "behaving like philistines" and blamed the issue on American Puritanism.

"Somebody's got a Michelangelo fan group on there and they do have a picture of the Statue of David. Why is that okay and this isn't?" she asked.
