Because of my personal situation I end up hosting at my house... When a provider is at my house there is little they won't know about me if they just bother to look around. Because of that I think turn about is fair play and that a provider should be honest with me. After all you are in my house. There are some who can not be trusted...I am not one of those, so I can understand the hesitation to over share, or even share just a little. But I do prefer a little honesty and forthrightness!
If you are hosting me at your place and don't ask me for my name, I won't ask you for yours. If you ask for mine, I will give it to you, but I expect the same from my provider.
Just saying...
