Communication via mobile number.
Photo - whatsapp pic
So you are not sure that she is an escort. And you post a picture off social media? Did she tell you that you could post this pic on a punters web site? or are you just outing some random girlfriend for revenge?

Naive, daft or dodgy - one of these.
