I guess you are right on this one Wander - I know I would be impress if some billionaire lady were to buy me a plane ticket to meet for the first time!!
Actually, like I said, one of the reason for me putting my profile up is for when I travel overseas to countries where I know I will get good response from the site and also like you said for privacy...my country is a small island of only 1.2million people, and there is always someone who knows someone who might know you...so I avoid mongering when I am at home, but when I am away on my own, all bets are off!
On the issue of the rule for civies, I think bro doghead got it right; I have heard of schoolgirls (aged from 16 to 18) who work as WG on the side in Japan to earn extra money to fund their habits of needing to have the latest fashion or technological stuff or mobile phone ...So it's possible it's the same in HK and other countries in Asia. From my experience, girls from Singapore, HK, Japan, Korea etc, are very materialistic, doesn't mean they are bad or horrible person, but they are money minded and always want the latest branded things - I have even heard a joke about Singapore girls on this - Some guy try to chat up a girl in Singapore, and the first thing she asked him "What car do you drive?" - And before anyone ask, I am of Chinese origin, so I guess I'm not being racist!
