Interesting idea, but seems like it could be pretty dangerous. If an attacker was able to figure out the subset of Tor users taking advantage of these special exits and ran one themselves then correlation probably wouldn't be too difficult. In addition, abuse issues makes finding exit operators a

I'm not sure that the correlation attacks for `bridge exits' are better than those for normal bridges. However, the `exit risk' would likely be more discouraging to such `bridge exits'. However, as a more general question, making the Tor network difficult to completely enumerate might be
