Likely legit, but...

...fake photo.  This is also a typical ad for Asian women that are being illegally trafficked for the sex trade.  I would highly suggest not being part of the problem and finding ladies in more legitimate forums.  There are also Latin women being trafficked the same way on this site.

Get the Tineye Firefox plugin and check the pictures. Invariably phony for these women.

ACS is what those ads are called in some other forums. They always use fake pics and promise the moon but the actual services generally consist of CBJ/CFS and wham, bam, and out the door asap. They are definitely high risk for trafficking activity although some are simply Chinese women from NYC that travel to different cities to (voluntarily) work as providers. And, no matter what the ad says, the women are ALWAYS Chinese. The problem is that there's really no way for a "Laowai" (foreigner) to know whether or not they're being trafficked. But the bottom-line is that everything in the ad is fake so there's no point in rolling the dice in the first place because the odds are stacked against you.
