Some people talking about this statement, which means people who running copy blogs should register the list of NicoNico.
Acutually, it's a licensee fee in point of fact because people who want to register the list have to pay 500YEN per month.
It was written by Hiroyuki. So, I think you can change this policy and make another license fee.
However, these sites are not whole copying sites, just summarise some threads.
I think it don't make a trouble.
