Everyone certainly has different requirements. They are different because it's what it takes to make a women feel okay enough to see a complete stranger, and that varies
As a hobbyist, if you don't feel comfortable with the screening, it's best and most respectful to not lie about yourself and then find another provider.
I do see that your full name could be useful for running a background check for criminal history. I suppose that's a valid reason, if that makes a lady feel safer.
Providers do and should create names for themselves to protect themselves from bad actors, most definitely.
In regards to giving out personal info, this is where being very choosy about the provider comes in. If I were a hobbyist, you can bet the only provider I would give my real name to would be someone with great reviews or a P411 member.
