This thread seems to keep getting replies, as it keeps getting bumped back to the top of the list. I'm not even sure why this is an issue at all. If some person asks me for info I'm not keen to provide, then they will be met with silence, and if they are particularly insistent on extracting the info from me, they will probably be told to take a hike at minimum.
If the info a provider is asking you for makes you apprehensive, then go look for another provider. One and done. I assure you, of the tens of millions of SW active all over the world at any given moment, not all of them will have identical protocol when it comes to the info they want from prospective customers.
I'm not going to get into too many details.... but within the last month I sent a message through a site to a delicious Hispanic woman in her late '20s. I mentioned that I'm aware short notice is not easy to accommodate, but asked her if she might be available for an appointment in about 6 hours or so from the time I was contacting her. She responded with glee, stating another client had just cancelled on her for essentially the same time slot, and would be thrilled to see me. She was able to view whatever info she felt like she needed through the site I contacted her on, and did not ask me to provide anything else other than the address of the hotel I was staying at, that's all. Didn't ask to see my ID, and didn't ask for my last name, and neither of those were visible on the site.
I didn't have a problem. She didn't call my hotel room land line, ask me what I looked like, or engage in any other behavior that felt like she was invading my privacy. And honestly, combined with everything else that happened between the afternoon before I saw her, and the afternoon of the next day, I wouldn't trade that entire 24 hour experience for anything - well, not anything I can think of at this point in my life. And NO I will NOT write a review about this woman; that's like sharing the location of a secret gold mine.
Just look for another girl who isn't as invasive, that's it. If there aren't any other girls up to your standards in your area, then travel to another city. And if you can't find one, well, sorry, I don't have any other advice to give you. I guess you could buy a love doll as an alternative; no screening required and an open key, pure cash transaction. That's about all I can say. Pangolier over and out.
