Why not use electronic fig-leaves?

On occasion the puritans come out and affix ribbons on sculptures of naked figures so the youth can not derive unintended/uncontrolled sexual jollification from the art.

FB could do the same. They could easily place electronic 'splodges' over the parts they decree to offend and permit viewers to be able to click on the 'splodges' so all is revealed to those who appreciate art?

One problem comes when addressing certain animals as the electronic splodge would have to be really large to cover an stimulated horse or bull.
