Sending mail originating with a person always requires human action. If one cannot be bothered to mark friends in his addressbook as humans (in fact, the very act of adding someone to an addressbook is sufficient, that information just needs to be processed). Do spammers have many friends? They certainly network. > The bigger problem is that webs of trust don't work. > They're a fine idea, but the fact is that nobody keeps > track of the individual trust relationships or who signed The point of an automated web of trust is that the machine is doing the accounting for you. > a key; few people even bother to find out whether there's > a path of signers that leads from them to another person, > or whether the path has some reasonably small distance. Human network connectivity have such properties. The entire graph is connected, and each person is reachable via a few hops. Given that there are only a few billion people on this planet, such a database should be quite easy to store and to query in a P2P fashion. It only becomes nontrivial when it has to distributed, and immune to content forgery and DoS. > I have not yet seen an example of "reputation" favoring > one person over another in a web of trust model; it looks > like people can't be bothered to keep track of the trust > relationships or reputations within the web. The real issue is whether people can volunteer information stored in their addressbook. Not everybody is an Orkut/Friendster/FOAF exhibitionist. -- Eugen* Leitl <a href="http://leitl.org">leitl</a> ______________________________________________________________ ICBM: 48.07078, 11.61144 http://www.leitl.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE http://moleculardevices.org http://nanomachines.net
