All good questions, I kinda figured that the girls rotate through about every week to 2 weeks. And either 1-2 girls. And most numbers belong to 1 handler so possible 2-3 handlers in the area??? Maybe??? This is just what I kinda figured out myself.
depends on the place and the demand and the attention...
the old nkc apartments turned over gals every 2-3 weeks, but yoga pants gal stayed for a couple months...
lulu got some attention here but moved around - and if you called the BP numbers of old you would stumble onto her new location (hotels) if you were lucky...
all of them have mamasans so to speak - and they have multiple phones - easy to burn them if they feel they are about to get burned - yet protect the operation...
lots of times the call generates a pick up and a drop at an incall location depending if a certain gal was asked for - so per your point i have always said "no lilly" if i saw lilly and was looking for something different - they can be accommodating if you just ask...
2-3 weeks is the average, but as others have noted, it varies. Multiple numbers/groups/ads are definitely being controlled by the same organization. I've confirmed that data is shared, and also noticed the exact same messages coming from multiple numbers. Note also that they do not delete messages or numbers.
