Funny that my first post is about a potential faker.
I did a reverse image search on her pictures, the first one lead me to another escort site, reasonable enough.
The 2nd one gave me a match to an image based site, which lead me to find an Instagram model under the name of Mariana Queiroz, who has over 65k followers. The picture appears twice in the insta profile.
The 3rd picture didn't give me anything.
She also has private pictures, but I'm not too keen on paying to do a bit more research, but I'd say it's someone who is pretending to be somebody else. Or a fairly popular insta model is also an escort, but I doubt it.
