To be honest, I have used the classic "Oh I am having my period on that day so I won't be able to see you." excuse many years ago. But they ALWAYS come back again at some point until you make it clear why you don't want to meet them again.
Now when I get an inquiry from a repeating client whom I am not willing to see again, I tell them the reason straightforward why I don't want to.
Most times they understand and respect my decision but sometimes it is difficult. Some of them even contact me again an year later pretending this is their first time to contact me.
I had a client who was simply too rough. I told him during the session to tone down. He said OK but he did the same thing in 30 seconds. It was a difficult date.
He came back next week to book me again so I clearly told him that he was too rough and I didn't like it. He said he would be more careful. Fine, I decided to see him again but the result was the same.
He came back again about a month later. This time II explained what exactly made me think I didn't want to see him again in professional way of course. His next message said he had so many other escorts he could call but he had specifically chosen me to spend money on so I should appreciate him. His message was concluded with "I will give you a chance to meet me and apologize."
I didn't reply. So yeah I have ghosted if this is what you mean by ghosting.
Another case with a new client is when he showed too much interest in bbfs. He asked me if I could provide bbfs. I said no. He said he was OK wirth covered FS but also asked if it is OK with me to remove a condom right before and cum on my body. As long as it is covered during intercourse, I am fine with COB so I said yes. After we confirmed all the detail, he casually asked me when my next period would be.
Probably he was still planning to do bbfs secretly maybe while doggy so I told him that I would cancel our appointment as I didn't feel safe to meet him. He sent me a few more messages trying to change my mind but my decision was solid. I am not going to see him period and he tries to change my mind. I didn't want to waste both of our time into endless conversation so I stopped replying him after a few more messages.
As a professional escort, I don't ghost without any explanation.
