If, this is genuine, and it seems a bit unlikely for her to go after every single person who calls/texts her, then it's a police matter.
What have you actually done, contacted an escort, from what you've posted you haven't even met her, so nothing has gone on.
If this is happening, and you give her anything, then it won't stop, once she's got you to do that then she has you, she knows you will give in.
Once that happens it's only a matter of time until it comes out, by which time you would have given her something, indicating you see you did something you felt that much need to hide.
Police.
