By Mark Ames for Alternet. Last month, the Washington Post gave a glowing front-page boost to an anonymous online blacklist of hundreds of American websites, from marginal conspiracy sites to flagship libertarian and progressive publications. As Max Blumenthal reported for AlterNet, the anonymous website argued that all of them should be investigated by the federal government and potentially prosecuted under the Espionage Act as Russian spies, for wittingly or unwittingly spreading Russian propaganda. It’s now been a few days, and the shock and disgust is turning to questions about how to fight back—and who we should be fighting against. Who were the Washington Post’s sources for their journalism blacklist? WaPo’s key source was an anonymous online group calling itself PropOrNot (i.e., “Propaganda Or Not”). It was here that the blacklist of American journalists allegedly working with the Kremlin was posted. The Washington Post cited PropOrNot as a credible source, and granted them the right to anonymously accuse major American news outlets of treason, recommending that the government investigate and prosecute them under the Espionage Act for spreading Russian propaganda.
