What are examples of Josh being gullible and easily manipulated? You are definitely correct, but it is a more subtle part of Josh's personality easy to overlook. I think a good example is his e-daddies like Dick or Rekieta and how he spent so much time going to bat for them and having his site attack their personal enemies (like Maddox or the Twitter lawyers Rekieta would argue with). Or conversely examples like how Josh was suckered (by his lawyer, or maybe his own hubris) into believing the Rekieta bodycam footage would be out any day now instead of being a nigh-impossible quest like even a non-lawyer could tell you.
Josh makes a great attack dog, and having a forum full of morons makes him even more valuable a tool. No wonder Gabe Hoffman has his hooks in him.
