The social media website's rules don't allow the uploading of sexually explicit and/or nude pictures.
The banned image belongs to Denmark's iconic 102-year-old waterside statue of the Little Mermaid, but Facebook thought the Danish national artwork allegedly had "too much bare skin or sexual undertones," Danish newspaper Ekstra Bladent reported.
"The Little Mermaid is simply too naked for Facebook," Danish MP Mette Gjerskov said on her Facebook account after several attempts of trying to post the picture of the mermaid on her Facebook account.
Facebook said it restricts nude pictures, because some audiences might find them offensive. According to Mark Zuckerberg's social networking site, the images of female breasts can't show nipples unless they're seen breastfeeding. And yes, this rule applies to art.
