I think it's obvious that the CIA or the Clowns, use Secure drop or the Apache.de anonymous frame work to post their talking points. If they are anonymous there is no culpability. Plausible deniability, as it were.
Is either system REALLY secure? if it's TOR based the answer would be no, correct? Because CIA has back doors to it. I am not as up on ToR as I cannot create the right environment to use it safely. But a real and I mean REAL WH could tell us and sauce it.
