puckipedia cwebber: the concern is that, say, I send a message to you directly. then we have some anti-spam central server, and you and I both run private nodes. We have the impression that I'm sending something directly and thus it's a private channel. in fact, this other server, the anti-spam server, would see the communication. you would have the level of surveillance Google has over Gmail servers, which is equivalnt to the privacy if you use the anti-spam service
