I have noticed there are four to five young ladies in Las Vegas that all sign onto P411 within a few minutes of each other every single day.
This has happened every day for some time now.

You can't control it - your only course of action is to alert staff/admin/whoever of the site(s) and appropriate action will be taken (or in more cases, not).  

it indicate they were managed or I was reading too much into it.

Speaking for myself on days I don't have plans I often check my p411 and other sites I use to advertise. So I'm constantly responding to board discussions and constantly making myself available on p411 when I really am. So I can imagine other ladies do this as well. I don't use a scheduler and I'm sure others that advertise similar as I don't use a booker either.. It may just be that we all are signing on frequently to respond or to create availability.

. . . .  "the group" and it may enlighten you a bit.

Let's not go there....again.

I know. I'm tiptoeing around the subject, because all of my posts about this end up getting pulled.

I know two providers who are completely computer illiterate and use a person to handle that aspect. Not an agency, just a paid secretary of sorts.

I am on there all the time I noticed that other's are on all the time when I am.

I have their app on my phone and it's as easy as opening my phone and clicking a button to sign on available now.
Therefore myself and I'm sure alot of other ladies sign on often so that You know We are Available Now
