Because there are asshole guys out there who will do horrible shit to these women.. given the chance. So ladies want to know as much as possible about a guy before they agree to be confined in a room alone with them. And thats understandable...
On the other hand you have a lot of scammers, and disreputable women trying to extort guys, or ruin their lives with the info they request...or, you'll get the occasional provider who just flips to BSC, and outs a guys info on Twitter because he chapped her ass on a given day.
Bottom line....youve got bad apples in the bunch on both sides fucking it up for the rest of us.
I have given my info out, when I first started doing this, and luckily, it never came back to bite me in the ass personally.
Now, I have a P411, and try to stick to providers who are comfortable using that for verification needs. But there are still an amazing amount of ladies who won't accept this as a stand alone. At that point, I have to decide whether or not giving more is worth it.
I have inquired to a provider in which I felt the screening was too light also. That caused me enough apprehension to pass on booking with her. She advertised as full gfe, but in my experience, the only women who screen that lightly have been the old BP fleet of providers. So, in my mind I was either looking at a BP level of service, or possibly an LE sting. If I get a bad feeling...I cut bait.
