IMO, there are a couple of possible reasons for Tormail's existence.1. Civic minded civilians. Yes, this is possible.2. An intelligence agency is doing something like the following:2.1 By analyzing the network topography of emails sent they can work out the relative importance of the users.For example, responses from a boss to most underlings are likely to be relatively brief, whereas a report from an underling could be pages. Even with padding, this could be obvious with a large enough sample. Of course it would be far more sophisticated than what I'm describing, this is just an idea. Basically the users sort themselves in a kind of pattern which can be interpreted.2.2 Then, once a target is selected, the agency brings the full power of a distributed network to brute force to obtain the target's private key. From then on, it is easy to exploit downstream.So, any plaintext intercepted from the naive is really just icing on the top.3. It is run by the equivalent of long con selective scammers hunting for interesting titbits for blackmail etc, esp. since almost certainly some pedophiles use the service. Given that I believe the RBN corporation controls this service, this would tally up. The US nationals might be in Germany, but I think the servers are in Russia.--Whether the reality, diversification is required. If SR is to come under attack then Tormail could also be a target. However, I think that will mean the FBI will have overstepped the mark into a hornets nest given who I believe runs Tormail and also the composition of Tormail end users. Unless 2.0 is true, in which case they could be negotiating some selective attack by removing SR accounts.Finally, while there are other services on the darknet that provide channels of communication, it concerns me that if you attacked two hosting services then it could make life somewhat difficult to regroup.Hence, we require a truly decentralized support mechanism that is easy to use, even if it's a bit slow. Do you have any suggestions? What about the Association of Aquatic Mammals. Can they help us? :)
