To earn money by fake news, you need to bet against the crowd that will act on the fake news, and you need to make the bets prior to the fake news. The crowd will lose some money on the act, if you properly blend in with them, you won't earn anything.

I mean, it's just as with the investigation of pump-and-dump schemes with the added benefit that after warrants to sieze and review computers you can also get some evidence of the hack.
