Linked Tor Relays To Bypass Probing?
As tor bridges are obtainable, one idea would be for a tor bridge to "link" with another tor bridge. Here, the bridges are obtained in pairs. What linking does is that the client has to send the exact message with sync(using different keys of course) to both bridges, after the bridges receive the message, one server claims the connection and then sees whether the other receives the message as well. This way, there are a lot more combinations to check for the censor.
