Do you ever have any issues from telling them? For me there have been a few guys I've not been sure about on 1st meeting but after 2nd meeting they've made my skin crawl. Also some regs I've sacked off for pushing boundaries
Generallly I don't give reasons. I block & forget. Have not had guys trying from different numbers but from the sound of it...it's not that unusual!
In a blue moon I tell them 'don't call me again' as they leave. One recent exception I gave him a reason so he could run and fuck off before I got hardcore angry ....he was a chimp who complained from the moment he stepped in about the the size of the apartment and numerous stuff. I told him to get up, put his clothes on and leave cause you've moaned the whole session. I didn't bother to finish him off and chucked his shoes out.
I'm not afraid of clients.
My feels are my job isn't to give them valuable personal evaluation to enable them to be experts at hoodwinking the next unsuspecting SW they ring.
I want them to stay obnoxious and shitty so they don't get bookings.
