how are they actively tying to stop it prof?
Almost all of the NE incall agencies use the same operating model, they have a bunch of permanent flats and different girls work from those flats each day.
Amour could do the same but haven't done so.
Many of their girls are outcall only, and those that do incalls work from their own flat that no-one else ever works from e.g. Amelia, Keeva, Mila.
Amour don't take bookings for incall duos.
IMO Stacey has her head screwed on and is trying to keep everything on the right side of the law.
There have only been a small number of their girls who have flat shared, and it has only started creeping in during the last 3-6 months as far as I'm aware. I imagine Stacey isn't very happy about it either.
