3daygetaway,
Actually, that was just one of a number of threads that have been in alert section. Some think it's the same person trying multiple handles, but who knows? There have also been times where a provider was not just robbed, but beaten as well. The point is it does happen and you never know who is on the other side of a phone call if you haven't already exchanged numbers.
Who is to say that when an established member calls that she will be in front of her computer to check your handle. If she isn't and doesn't remember your handle should she still answer your questions?
It just seems easier to me to look at their ads/showcases/websites and decide if I want to see her and go through her screening process. I have never had to do anything other than pm a provider with my phone number along with whatever other screening info she requires. When she is satisfied that I am legit, she will usually call or pm and then I feel free to talk to her about anything and everything.
I guess we will just have to disagree on weather or not a provider should discuss services with an unknown person over the phone or not. No one has any idea how many times LE or someone impersonating a known member gets hung up on or is told I don't discuss that, because they, like you, will not call back. Even if the chance is slim to none, I don't blame them a bit for being over cautious.
This business is risky enough, if I was a provider, I would want to avoid being arrested, robbed, beaten or worse at all costs. Even if it is at the cost of loosing a POTENTIAL opportunity to gain a relationship, which may or may not come to be anyway. But that's just my opinion.
