Pretty sure it's a rehash of the infamous asian mistress again. Ad is exactly the same, just changed the pics. You'll notice the rate will randomly fluctuate from $260-300/hr which is exactly what the original advertiser did as well.
Isildur is in the market for an Asian Dom, eh? Have you ever tried mistress Miko? I have never seen her, but it's the first name to come to mind. I hope you are able to find one, bud.
