So the "Chinese Wedge" was used for a spammer to gain a foothold. To sum, a wedge (hjclub) gained a certification from a Master (atai), who is Taiwanese, by presumably [mis]using some Chinese codeword. Then it certified normal spammer(s). The response (by chalst) was to call for ostracism, or a purge, which is the normal social response. However, suppose that there is no way to make atai to drop the cert of the wedge. What then? I think we ought to get used to the idea of imperfect protection. Raph actually said that in the book example some books will be given away improperly and that is all right. Still, there is probably some fertile field for research here...
