So I have seen lots of out call ads and have even tried one or two with mixed results. But I keep coming back to Grace's ad. 703-XXX-4617. Can anyone provide any insight? Thank you.  

she and all of the girls using this format are ripoffs. Pic likely not hers, shows up takes money and thats it...she'll talk to you for  an hour but that is it. Avoid any and all using this ad format.

There are legitimate ads on BP but you must verify each and every one of them..On TER or somewhere else. If you cant find anything the cardinal rule is wait and see.  
I know its hard lol

Link to some hits on her photos:

This is a ring - who post $160 per/hour fake ads - the photos are someone else - when the girl arrives she's nothing like the one in the photo - demands cash upfront - phones in her location - says she has a driver/bodyguard - and her services are for "chat only"....they pray on the newbies who don't know any better. They take the cash and dash off. Stay away - or give them a phony address and run them around all day long.
