First I know a provider can ask for anything they want to make them feel comfortable in their screening. I can also provide the information I want to provide and nothing more.
So I've been in the hobby for about 15 years, I've been on here just about since its inception, I have 47 reviews and 1800+ posts, and I have P411 with 20+ OKs.
So today I contacted somebody that advertises on this site (not all that often but placed an ad very recently) and she was adamant that for screening I provide my full legal name and my phone number. There was no interest in the other methods of screening that I mentioned above. This was pretty much a first for me in all my years of being in the hobby. I made sure that's what was required and then let her know I wasn't going to provide that information to her or to anybody, and I thanked her for taking the time to respond. It was all cordial.
I know this is somewhat unusual or I would have experienced it sometime in the previous 15 years. Again I know she can ask for whatever she wants but what would she get out of my legal full name and phone number that she couldn't get out of the other, more acceptable sources for screening?
