Basically the predominant number of the women on Profile are the manipulated 'Characters' of the local Agency they appear onto iDate. There are some few Agencies (not the bigger Chinese owned and named ones) that have listings of real people. Look for the Profiles with genuine 'natural' pictures, rather than the artificial Studio pictures, done by the Studio attached to the Agencies. Also look for the context of dialogue in the Profile. Areal person's description will most likely be awkward and stilted in English, whereas the dialogue that comes out of the Agency manipulated Profile persons is generally all flowery, suggestive and 'lovey-dovey'.
Mainly the Profiles on these sites are falsehoods and a simple money making scam.

This is the biggest scam site in the history of on line dating! Contact siriluck@hotmail.com.Tao & her husband have been my best friends for 13 years. You will be able to skype ladies of your choice. Tell Tao what you are seeking & she will provide photos. All this is FREE! However you will be expected to pay about $50 if they collect you from the airport & take you back to their city (approx 250km's) If you require more info feel free to contact me gjk1949@hotmail.com

The site is not legit. Don't waste your money on it.
