Why would you give somebody your address/ personal email or non work phone number unless you wanted them to contact you in the future. That said as time passes and people move on friendships no matter how close tend to wither.
I am fairly certain there are some ex escorts who have new lives and have buried there past in a big hole.
To be fair you'd need a phenomenal knowledge of comings and goings to be able to comment with confidence on a significant drop-off rate. I've noticed girls disappearing off the radar - sometimes for good - over the years but never had enough information to say if there was a surge in this activity in a particular place.
From another angle...…………..it is August and people tend to go away during that month.
I prefer to stay silent on topics I know nothing of tbh yet will always have a zest to gain an understanding of things I have no knowledge of yet there are things one can never fully understand like the life of an escort as we cannot walk in their shoes which is why I stay pretty quiet on saying anything when it comes to their world.
