They're probably being extra careful to protect themselves from defamation lawsuits. I have more trust in the information reading this, because I can assume they're willing to say things that put them at risk of being sued by powerful organizations.
As honest goes: "We are an op-ed oriented information sharing site. We do not adhere to normal journalistic standard."
If the misdeed is done by a non-public or poor company there is no money to be made so they would never even investigate it. And not accepting a payoff that returns more than the short position would be ignoring fiduciary responsibility, so some investigations could disappear.
