Dude take this how you will but this post really ISN'T the exact same question.
Your original thread was about provider X hounding you for screening info after you contacted her from an unknown (to her) phone number. She was stupid to answer your question without verifying who you were to begin with. You are stupid for not taking the easy route and just giving her your previous number from the get go. After both mistakes it just turned into a dumpster fire that shines an unflattering light on you for not just letting it go. It just comes off obsessive and immature. I am not saying that is who you are IRL but that is the impression these events are leaving on people.
As for the topic of THIS thread.....do what you are comfortable with if someone's screening isn't to your comfort then move on. The same goes for providers. If someone doesn't want to be screened to your comfort level then they aren't the client for you. I know I personally require a lot but I've never had anything but perfectly friendly, respectful, and wonderful times with newbies that went through my screening and I want to keep it that way.
Just my honest, unvarnished .02
