The Supreme Court just ruled that "community standards" can't be ignored when the ACLU tried to prove that censorship of images of nude children is a violation of free speech, and the Supreme Court sent such a case back to a lower court for review on those grounds. If the "community standards" of 'rosity are determined by a group of administrators, then they will eventually have to be consistent with each other, which will probably require them to either allow or ban all nudity, unless they develop specific standards that aren't secret, arbitrary and capricious.
