You may be reputable as I'm sure are several others. But until I find that out in person, some of us have as much or more to lose with respect to lost anonymity and reputation as said reputable ladies
I don't give out my personal number any more than I would expect you to give out yours. I'm harmless and very pro-SW... in fact, IRL I'm usually told real names (curiosity on my part to see how it matches the person) and I reciprocate and give mine. Several have become FB friends even, but in the beginning, my guard is up as should that of all SP's. <3
In my experience, albeit limited, a lot of European talent and some SP's (i only know a few there), use WhatsApp to communicate, especially when a lot of the girls come from out of country to work as do many of the clients. Personal info is personal info. And it's not a comparison, but it's likely that getting outed for me would have far greater consequences than the same for you. A cautious client might see things in the manner I do more easily than the manner you just explained. I know some rather famous people where privacy and discretion is paramount, and I've facilitated various things for them. The irony is that they do not know to what extent I'm involved on the back end, nor do they ask for the same reason I hold their anonymity and privacy sacred. And yet if we were to ever meet, the likelihood of you telling me certain personal things about you and likewise for me is higher than average
