Why advertise …..

Why do women advertise and nothing in their advertisements says not seeing new clients . Making a trip to Birmingham 1st of the week and I have inquired through email with 3 from tryst in Birmingham and all three says not seeing new clients. They were real nice about it and I thanked them for their response but why advertise ?
I would guess they put the ad up some time ago and it's easier to just keep the ad up and cherry pick the responses than it would be to just post the ad and hope to have someone respond when they desperately need a new client.
