Japan's own black list database system, the "RBL.JP Project" has been formally launched and is steadily progressing. We will be distributing information by means of a mailing list. We are still accepting applications (Japanese mail form) for volunteer programmers, web designers, database engineers, people who can translate RBL.JP documents into foreign languages and those knowledgagble about relevant legal issues. These are non-paid positions. Goto here for more about the recruiting of volunteers in English.
