What is real?

I saw a picture of this girl - the first picture in the set (which is all over the internet as she looks so cute in that picture), and liked the girl, so went looking for more. There are pictures of her scattered all over the place - under various names. Even on an escort site as Lucy a French prostitute. She looks to be somewhere between 18 and 20 years of age, and took most of the pictures herself, uploading them to some chan site for the thrill of it - or perhaps to please a boyfriend. She appears to have taken a number of shots over a short period of time, as there are a good number of different sets, but she doesn't change much in appearance - same hair style, etc. There's a few non-nude shots which she didn't take herself, including one at her college.
