Japanese on E&B how to find out who is *actually* working?

I've noticed that whatever the manager is for the Japanese girls hosted on Margaret street and else in the CBD never discloses who is actually working, unlike most other asian providers who happily give a daily menu/list, or if you request it. Does anyone have any intel if there is a central place to find out, please? Been using other more reputable groups and haven't given this provider a chance for several months since they always bait and switch with another (but real with an existing ad on EB) girl. They usually use a cuter girl who's getting more attention and direct some of that traffic to less popular girls. I still peruse EB now and then, and Amber (https://www.escortsandbabes.com.au/P...nt/bbbbne2006/) looks really cute and I want to book without getting my time wasted. If I have to walk then I'll walk. Wondering if they also operate on wechat/telegram/line?
