BASED ON SUGGESTIONS from Gavin Sheridan about the ever-tightening rein of censorship in the Arab world, I have started including people as "family" members on Flickr. Stuff annotated as "family" is never seen by censors along the way. This is important when dealing with any photos featuring poses that reveal shoulders, legs, or feet.
Countries such as the UAE, politically correct corporations and some ISPs have blocked Flickr for "inappropriate content" which has led to hard-core Flickr members to share work through family nodes. All photos featuring frontal nudity should be shared through "friends" and "family" already. Nude curves (belly tops, builders' butts and body piercings) need to be treated that was as well.
Flickr is currently restructuring server architecture that facilitates even more flexible filtering in the future. That's essential because Flickr members don't want a censored (read blinkered) perspective through the viewfinder.
