And I believe there are some computational complexity results on the relative difficulty of obfuscating vs. detecting obfuscation that strongly favor the obfuscators. Even in a simplified model of stenography, I have to imagine that the detection problem is at least NP-hard. Yes, but that is at best looking for needles in a haystack.

By analyzing the results of those queries, it might be possible to get the messages prior to the persons it was intended to reach.

Sending encrypted emails to or from benladen@gmail.com just does not make sense.
