You seem to be saying that the subject of this post had sex to progress her career. What evidence do you have for that claim? That is not what she has said at all.
There will be a degree of agreement from some of the females, yes - but generally that is not why they left their home and came to another continent and it is not even remotely close to their true needs or desires. Usually they are lied to to at all the points in the process and that is the point here. In the case of Jeffrey Epstein, it was stated in court that he threatened people with violence and death if they went against him.

Since this is the only example I can think of, of a successful 'top' model publicly stating that organised child abuse and prostitution involving governments occurs even at this 'elite' level in modelling and she intends to stop the situation - I am clear that this fits the description of a whistleblower:

One who reveals wrongdoing within an organization to the public or to those in positions of authority.
n.
Alternative form of whistle-blower.
n.
an informant who exposes wrongdoing within an organization in the hope of stopping it
