The phone # listed in the ad looks like an agency #.  The ad is written in the third person, meaning someone wrote it for her.  That may be because she's from Brazil, alledgedly,and therefore may not be fluent in English, but it could also mean she's with an agency.

If you read the Las Vegas board, they say she's from LV, then you know that virtually all agencies in that town are rip-offs.  I would have doubts about seeing a lady that was associated with a LV agency.

But, hell, she is nice to look at, so if  you want to take one for the team........

Just my .02, or whatever it's worth.
