Jim-san, no general volunteers need such a paper.
Just 2ch operation guys ( ひろゆき、FOX、むむむ etc) need it for bbspink server setup and maintainance.
The purpose of the paper is one thing;
The paper would be used as a powerful shield protection for them
when policemen ask them on thier standpoint on bbspink operation.
Because the paper could work as a good evidence
that shows they perform the operation based on your request, not their own intention.
It's important for them to be secured from legal risk.
Anyway, I recommend you to talk with them offline.
