Short answer is no, nude photography will be covered by the NSFW curtain for those not registered. They can be viewed by those that opt-in to see them once registered. Natural next question is...why?? - and the answer is that this site is funded by advertising and advertisers require brand safe environments to show their ads, but also - there is a segment of the photographer population that prefers not to see nudes automatically and prefer to opt in or opt out of seeing them. I know its not the answer you wanted, but it is what the principals of the site decided to do years ago to comply with advertisers as well as address concerns of those not interested in seeing nude photography.
