Sophine while I can understand your annoyance with these idiots I don't think what you do is wise at all. It's never occurred to me to take revenge on any time waster. I'm just glad I never met them and not likely to after they're blocked. They can try again with a new number and there's nothing to stop them but you finding it hilarious to get them back is a waste of time (which could be spent doing much better things).
I find it enough to just call them f@#@#@ c#@#s to myself.
No, because even if it was a worthwhile use of my time, one 99p SIM later and I could be alone in my flat with some psycho. I have hobbies instead 
This and this 100%
And as well as those comments I will add that this is the kind of behaviour that's puts us all in danger and gives this industry a bad name, it's why most people think all escorts have mental health issues or are on drugs and feeding a habit, frankly I find it slightly bloody unhinged if I'm honest

.
Block and move on it's simple, then if you have too much time on your hands, which it would appear you do, go out for a walk, take up a dance class, read a book or 1000 other options other than this and tell the mates who are doing it or putting guys on guy sites to do the same.
Good god that post ground my gears, OK rant over
Peace and harmony to all
