Dummy up. If it's not reported, if it's not news, it didn't happen.

Pizzagate was reported, but the vast majority only got the MSM take on it, which deceived them or made them doubt other independent sources.

Characterize the charges as "rumors" or, better yet, "wild rumors." If, in spite of the news blackout, the public is still able to learn about the suspicious facts, it can only be through "rumors." (If they tend to believe the "rumors" it must be because they are simply "paranoid" or "hysterical.")

This one is the worst.
