Wrong way of thinking. Outside SG, the process is like this:
1. Pretty girl wants to be a model
2. Pretty girl PAYS A PHOTOGRAPHER (in cash or... well, depends on the country) for a portfolio
3. Pretty girl brings this portfolio to all the modeling or casting agencies in the phone book
4. Pretty girl may need to continue to pay for updated portfolios
5. After all this investment, she may have a chance at a professional shoot in a magazine or a print ad.
This is how it goes in SG:
1. Average looking girl figures that when she's at Sentosa, the old uncles take pictures of her in a bikini anyway
2. Average looking girl posts a "wannabe model, pay me!" ad on CS
3. Many CS people think this is the correct process and pay hard-earned $$$ to the no-talent, no-looks, no-training model wannabe.
4. Photographers post pictures of these girls on a public forum, making the girls feel special and ego-bloated by posing "wow, so chio" posts, while people from outside SG see the pictures and think "are these guys desperate? Where are the pretty girls?"
Great Summary.
You can only blame the "photographers", they are the one who make the girls think they are "models". They offer to pay the girls for shoot, teach them how to pose, take nice photos of them, give them photos for their portfolio which they can further use to advertise themselves and make more money...
