Mind you, any proper psy-op (and Microsoft astroturf campaigns don't count) wouldn't just parrot the propaganda line of its sponsors, but would speak mostly truth or credible propaganda from who it's meant to be, with the odd strategically placed nugget of disinformation, whose power is magnified by its prior credibility.
I believe that's how WW2 Nazi disinformation agent William "Lord Haw Haw" Joyce's radio station operated; mostly credible/verifiable information with elements of disinformation/spin to demoralise the Allies.

Another case that Salam is real.
Well, if people can blog from Albury, why not Baghdad?
Well, Saddam's secret police are a bit more anal about these things than the Albury one.
This discussion has kinda been done to death already on Dear Raed. If a CIA/Mossad psy-op, he seems remarkably anti-war. If an Iraqi Ba'ath agent, he seems remarkably anti-Saddam. Maybe he works for the French :)
