From the comments we post, to even the picture, does and will colour someones interpretation of those here. If you like, a stereotype will develop, we can either try to take control of that, or we can let it be set by the media and the few who do not represent us all. The Moderators, I think, have taken steps to halt a direction that might not be in the best interests of all, while trying to not stiffle creative talent and exploration of a photographic genre.
I started the thread because my response to Vince's underage comment became too long and I did not want to usurp a thread where someone was looking for genuine feedback on their photos. I do think certain shoots are "age" appropriate. And that models of a certain age should not be in certain shoots.
Again, if this makes me a prude then so be it, but I feel there is both a legal basis and a moral one for my thoughts. Your morality is your own and you are free to disagree.
As for defining what "obscene" is, are you asking for the legal definition as defined under Singaporean Law or my own moral benchmark?
