I agree with most of previous answer
[QUOTE=ThrowAway3000;6499241]What are the red flags?[/QUOTE]It is hard to say that a non local number is a sign of a scam because of girls traveling to other locations.
Sometimes everything listed on the menu means the girl is lazy. From what I understand is that when they create an ad the default on ATG is everything.
One good thing to do is conduct a search on the images. If they are used all over the country then it is probably a scam.
Also be very leary of new ads and ads where the girl says they are available for a short time.
There is no 100% solution so keep up with reviews and listen to your gut. Listen to your big head not the little one. You hold all the power.
