Statistical analysis is probably easier with a larger number of nodes, if you're talking about your direct peers monitoring you. Also, Freenet 0.7 supports opennet. And "same darknet"? What's the same darknet? There is only one 0.7 network as far as I know, although there maybe secret ones. If there are secret networks of 15 nodes, the NSA would probably not be on them. The long-term objective is to have a globally scalable darknet, which means that it might have a million nodes in it, but it's all going friend to friend to friend to friend. Read up on small world networks. Frost works better on 0.5 because the spammer has been attacking 0.7's Frost with constant denial of service attacks, not 0.5's Frost. They are both just as vulnerable. FMS is the solution. Darknet came up well before the collaborative censorship ideas you refer to, and that wouldn't be Freenet, it would be a different network. There is absolutely no intention for Freenet to provide any sort of censorship mechanism, and it doesn't provide any.
