"When we looked at it later, her tan line reminded us so much of the famous Coppertone ad."But whether the photo was planned or not, it's against the rules.

"Facebook has a strict policy against the sharing of pornographic content and any explicitly sexual content where a minor is involved," the site's community standards page reads.

"It may be that we have to negotiate with our kids a little bit more about what’s acceptable or not or give them the ability to take down photographs they don’t want there," Balkman said.

Ultimately Facebook, Instagram and other social media sites are rapidly trying to expand their user base, capturing younger and younger audiences.

Anything we post illustrates a broader point about our civil liberties.

And sure enough, this particular naked statue did just that by serving as a touchstone for a conversation about community standards and censorship. Instagram (which is owned by Facebook) also came under fire last month for taking down pictures of topless women.

In its defense, Facebook said that such disturbing imagery was allowed with a warning preceding the video and could remain on the site as long as people were "condemning" the act, rather than "celebrating" it.

But critics argued that the video would be much more scarring to a child who stumbles upon it than any picture of nipples.

A professional photographer was temporarily banned from Facebook this week after she posted a photo on the Coppertone Facebook page of her two-year-old's bathing suit bottom being pulled down in the style of the brand's sunscreen ads from the 1950s.

(In her version, another young girl in the same bathing suit was the one doing the pantsing.) Facebook pulled the picture and blocked the user from the site for 24 hours, prompting a chorus of complaints citing the artistic merit of the photo.

Once Facebook realised their mistake they restored the image and apologised to the poster, a spokesman told Gawker.
