Re: Stating the obvious.....
So you're saying instead of publishing contact information, globally require that every single internet entity follow the exact same contact standards (they must have an abuse@ address).
To keep this short let me just tell you that will never work. Which is why WHOIS exists, which is why organizations can set contact information which is valid for their particular logistical model.
The problem is people register domains and they never bother to set or check their contact information, or they don't understand that it is public. So because a lot of people started playing with toys they don't know how to use, those of us who live and work in this world have to suffer.
